How's your guys' part-throttle? Normal driving around town?

Can you compare it to your previous chip? And state whether apr, giac, etc?

How do you have your wastegate controlled?
Stock n75
n75/mbc
mbc
ebc

mostly concerned with the gt2871r elim users....
does boost always shoot up? or can you hold say 5-15psi if needed.

thanks in advance

i dont have a bt but i have a k04 and i just started using a forge mbc along with my stock mbc and i must say that it is not as easy to keep it from boosting all the way to 20 psi as it was with my stock n75 or my ecs race valve.
most time i can keep it around 5-10 psi but sometimes(specially when cold) it goes all the way up to 21psi.

My driveability is great. I run just a MBC with the N75 plugged in and looped and I have part throttle. It drives nice around town. I love when it dips into the boost and you can just feel that the power is there.

I think driveability is great! (I run a MBC).

At part throttle it will probably get all the way up to 20, but that really does not matter, as the 2871 takes some time to spool.

So if you are going 25% throttle @ 2900 - 3500 rpm, you probably won't make it to 20. If you go any higher thats because you wanted the power hahaha.

The power it makes at part throttle is more than enough to skoot around cars.

I was worried about switching to MBC, but now I see it really wasn't a big deal.
