JHM Shoutout!

[oef_vet]

So I finally got my JHM Tune, FI Catback and Piggies installed. Wow is all I have to say. The car is completely different. SO much more throttle response. So much quicker, so much more fun! Thanks to Keaton for all his help with my incessant questions.

If you get any other tune for your S4 you're crazy. THIS is THE tune to have. Thanks to JHM for an amazing product!

after 5 total years spent in combat zones this is a given, witch is why I'll probably get either UNI or MRC.

I drove around with just piggies and FI catback for 4 months. Then I got the JHM tune. WOW. I was forced to punch myself in the stomach for every day I didn't have the tune. Those 3 things together make this car proper quick

I fully agree. being someone that has sampled all the tunes the JHM was so far ahead of the rest it was crazy.

i know its not recommended, because of constriction above 5500 rpms, but how is the jhm tune on a stock car? anyone done this? i dont have enough money to get all three at once (or two even if i gut the piggies) im saving for services before upgrades as well.

Its fine. The ECU will pull power to keep the car safe. For the max power pull the Pre cats out and get a solid 2.5" catback with a X. That unlocks the larger section of the JHM tune. As now the motor can flow better and make more power.

Keaton from JHM told me that you can do the tune first if you need too and when you get piggies or the cat back the Tune itself will adjust to the new mods.

Piggies alone will make a huge difference

[SpeedETC]

Good stuff OP. When I finally got the tune I really had to kick myself for not doing it earlier. I already had a tune on the car and was completely amazed at the difference.

It will. Its the only tune that will adapt up when you reset the system after a performance modification.

You would definitely know Didn't you switch from another tune to the JHM

How do you properly "reset the system"? Is there another way besides unplugging the battery for 30 mins?

when you reset the system by taking off the batt terminals make sure to touch them together for 45sec. This will prevent you needing to keep the batt unplugged for 30 min.

You can also hit the reset codes (even if you have none) in vag com
