    APR Stage 1+ (so with new fuel injectors)

    Guest-only advertisement. Register or Log In now!
    hey I am planning on doing the APR Stage 1+ with fuel injectors next week and was wondering if anyone was having any problems with their Stage 1+ and if there is anything important I need to know about doing this. I just go my A4 so I'm a little new, any info helps.

    Thanks

    change your coils... our years (so ive read) have a problem with our coils going bad.
    i got the freetrial a couple of weeks ago and withing hours i had a check engein light. the next day i had bad misfireing i took it to the dealers i had 2 bad coils and 1 broken check valve they charged me 550 to fix it but its cheaper if you do it your self. itll be 140ish to get 4 new coils and check valves are about 70 each. my check valve broke because it was already old and dry rotted so if yours are fine dont worry about it just keep an eye on them ...so basically change your coils and check your valves or anyhting vaccum related and you should be fine

    dont bother changing the coils unless they go bad.

    Go buy a few E revision ones just incase they do decide to crap out on you

    APR Stage 1+ is pretty bulletproof.

    And it is always a good idea to carry a couple of spare coilpacks in the trunk.

    They act just like lightbulbs... they can pop at any time without warning.

    Re: APR Stage 1+ (so with new fuel injectors)

    Going to 1+ isnt a big deal, but blowing 20+ lbs of boost will surely expose weak points in the A4.
    In my case, when I went from GIAC Stage 1 to 1+, I had the hose clamp keep blowing off from the intercooler to the throttle body when ever I got into the turbo, then a coilpack went (same day), then I developed a boost leak that I still cant find (but havent been looking too hard, either)
    Gas mileage will be worse if you dont drive like an old lady, too.
    Upgrading your DV will be a nice insurance ppolicy and changing your spark plugs will help, too (although AWE keeps telling me the pinging is NOT the plugs fault...)
    Otherwise, makes for a great daily driver!

    Re: APR Stage 1+ (so with new fuel injectors)

    coil packs, i popped two of them the day i got my old apr 1+ flash. i never go anywhere without a set of 4 new ones in the trunk.

    the red capped packs i'm running now (think i got them from ECS) have been great and are running strong for a year or two now but i still have a new set on standby in the trunk.

    Just remember without a turboback and FMIC, your EGTs will be through the roof and you will see very high correction factors in the timing.
    What does this mean for you? It means your engine will run lean and ping...I know this because this happened to my car for the 7months I ran the car without a FMIC. I had everything else besides that tho...

    you can run it at as and enjoy it but during the summer your will NEED a FMIC and a cat back exhaust. If you can, a test pipe will further reduce your EGTs

    Check valve for $70? Was it made of pure gold? Or maybe we are talking about different check valves?

    Re: APR Stage 1+ (so with new fuel injectors)

    yeah so i went up to APR today and got the 6 hour free trail just for the stage 1 chip. I thought it would be fun. Well about 15 minutes into my drive I blew one of my coil packs. haha so i just ended up buying 4 STI coil packs and putting those in. hopefully they will hold for awhile.

    front mount intercooler.

    keeps ur intake ar temps low. hot air means ur not using the potential.


    as simple as i can put it. anything else is discussed throughout the forums.

    Front Mount Inter Cooler. It helps the engine cool down better allowing more cold air. You should do it when you get stage 1+.

    ^^ you might be learning things the hard way on ur car man ... a FMIC is a Front Mount Intercooler
    It cools the air going into the turbo which is very hot considering it uses the exhaust gases to spin the turbing (turbo lag) and you need it because ... summer = hot outside and hot outside= hot engine and hot engine = bad stuff

    Re: APR Stage 1+ (so with new fuel injectors)

    FMIC and exhaust and BKR7E spark plugs... If not you will detinate or spark knock as i say. I did the exhaust and colder plugs and it has helped alot but next summer is FMIC. oh yeah I run 20 psi with the 1+ with spikes of 23 so it is a big difference for the little K03.

    Re: APR Stage 1+ (so with new fuel injectors)

    ok so i'm a little confused. I was talking to the APR guys and they never said anything about FMIC or that other stuff. After my coil pack went i was asking them a million things about if i had to worry or do anything else if i got the stage 1+ and they said no that the rest would be fine how it is. So do i really "NEED" to do a FMIC or is that just going to give me more power. If i can't really do the anything else besides for the chip and fuel injectors do you guys think that i should still get the Stage 1+ or not do anything at all. I can't really afford to be doing more than the chip and fuel injectors right now.

    How much do FMIC's cost?

    And why might i be learning things the hard way on my car?

    1) FMIC or DSMIC will reduce the heat stress on ur motor BIG time. For me it was in the order of over 30 deg C or about 55 deg F.
    A good IC will allow u to accelerate multiple times in a row without loosing power due to the hot air being ingested by the motor.

    2) Exhaust system will allow ur hot exhaust gases to flow smoothly through ur turbo. It will not only prolong the life of ur chipped and "stressed out" turbo but prevent premature failure due to constant heat build-up.

    Those 2 are the minimum mods/upgrades I would do on a chipped A4 not to talk about the clutch, brakes, suspension,... sooo yeah u are "learning things the hard way" IF u act b4 u learn all the stuff about how these cars react to mods.

    My tuner told me I didn't need cooler plugs... ha I didn't; but the car runs better with them.

    Another example almost everyone here has blown coilpacks in the process of chipping their cars... I haven't bcs I upgraded to Hitachi coils from ECSTuning over 10k miles b4 I chipped.

    Re: APR Stage 1+ (so with new fuel injectors)

    oh i see. Well i right now the car is still stock besides for the coil packs so i'm trying to learn before i do the upgrades.

    I just can't stand this car stock. haha its soooo slow. So do you all think it would be ok if i did the APR Stage 1+ now and then this summer do the FMIC and maybe Exhaust. Its just that i'm in college now and don't have a job at the moment so i would need to wait till summer to start making money again for the FMIC and Exhaust.

    Along with that if i did just the stage 1+ now and wait on the FMIC would my A4 be ok on a long drive from seattle down to denver or should i really have the FMIC for that drive? I have to make that drive in a bit.

    Thanks guys for all the help. haha sorry for all the questions

    Re: APR Stage 1+ (so with new fuel injectors)

    do 1+ and a new DV now. i have a brand new APR R1 (new version) i will hook u up with if you want. just PM me.

    you can get by without a FMIC for now (at least through winter) i did for awhile, however when you do get a FMIC, put it on, on a cool day and you will be amazed how much harder the car pulls..... if you can, just do a test pipe for now as well. you can get by without exhaust. some people actually think it hurts the k03. i couldnt tell any difference after adding exhaust

    1) Like Papachristou said look into a test pipe if ur state emissions allow... seems like u want ur car to drive faster for less than $1k here is what I would do:

    APR Stage 1: $500
    Test pipe: $100 - 200
    DV: $120
    Snub: $40 (NOT APRs crap snub)
    Get ur FI later & upgrade to Stage 1+ (mine was free + FI cost - $340 for 386TT. Seimens 380s are good too for cheaper stay away from Genesis 380s with the APR tune though)

    2) Frwy driving is not harmful on a 1+ its the stoplight to stoplight and full throttle acc that will really heat things up in there

    Stage 1 is pretty smooth without an intercooler with the 1+ it will feel like ur car slammed into a wall @ anything above 4500 rpm with the heat soaked IC.

    Re: APR Stage 1+ (so with new fuel injectors)

    Depends on how many miles on your car. Low mileage should be okay, but if you are mid 50's or higher, you should definitely upgrade your DV to handle the extra boost.

    Definitely skip the Stage 1 and go Stage 1+... really feel the difference.
