Modification really work??? Not sure
Please help!! I own a 2008 6mt s4 how supposed to do 0-100 in 5,6 sec stok. I do this mod; unitronic stage 2, apr full exshaust and downpipe and cold air intake.... The result with g-tech first generation, a beautifull 5,6 sec 0-100 and a 14,1 sec quarter mile!!!! The car feel very more furious than stock but...
Wow, is there something i mess...
Car is on shape with only 60000km and never see winter

I'm not sure about the tune, the best way to get all the answers is to call or email JHM directly, they're great bunch of guys
From what I know the best way to go with JHM tune is 2.5 cat back, at least piggie pipes (gutted precats). With this setup you'll believe in moding

I tink your right but i got 2,25" res catback and 2,5" hiflow cat downpipe... They cost me about 2500$ for both.... Hope i can keep this one and get jhm tune working great with.
Contact to jhm is done now, tanks for advice!!!
By the way, did you test your s4 and what kind of mod did you put in???

I think you should be fine with your exhaust set up the way it is.
But the tune is a must, I think it's 500 + shipping -and your car will be out for about a week, but trust me it's so worth it

Tanks a lot man, i had put my s4 on sale and check for rs4 like i was expected to ... Quebec dealer told me rs4 was too much expensive to run and at least 15000$ more expensive but now i find a few 2008 rs4 with only 70000km about 45000$.
After that i will tune with jhm like you said, it really seem to be the best!! Unitronic are good for the sale but the result frustated me a bit...

Unitronics changes less than 10 parameters. JHM changes about 140 parameters. No surprise the Unitronics tune does absolutely nothing. It'll make the throttle feel a little more responsive, giving a simulated performance feel but that's all it is, simulated, doesn't actually do anything useful. Kinda dishonest if you ask me but people will buy their product because they don't do their research.
With a JHM tune, 2.5" catless downpipes, 2.5" catback, JHM light weight crank pulley and JHM light weight rotors, you can enter RS4 territory. Plus, the JHM tune gives you Launch Assist.

im waiting for jhm answer, but if i cant run the tune exactly with my exshauts setup, then my car is for sale!!! at least i can cancel my apr cat from my catback, but investing on a second exhaust line when mind are only 1 month old is out of my religion...
