thats cool, is thier anything else i should get when getting the chip, i mean i have magnaflow, and i was gonna get an intake maybe, how much horsepower are we talking about (at the wheels) with the GIAC chip and magnaflow catback???

 

Haha how would a s4 chip work in a a4, the a4 has 2 less cylinders and 1 less turbo, the maps are not even close.

 

wheel hp I'm going to say around 160ish I would also recommend a upgraded Diverter valve to hold the extra boost you are going to get from the chip as for the intake do not waist your money this will not give you noticable gains if any at all and if you still have some cash to burn at the end of the day look into a boost gauge this will help out down the road with any boosting problems and it is also cool to look at

 

160 thats it, on thier website it says about 38 hp gain, thats about 208 at the fly, realistically that should be about 170 at the wheels with no exhaust i mean, do audi's have that bad of a drivetrain loss???

 

all all wheel drive cars have a bad drivetrain loss around 25%

 

ouch, that sucks

 

but you also get the gain from the launch at the light when your wheels do not spin thtsi is a big problem with FWD cars

 

I think you have gotten all the right advice, please let us know what you end up doing, it will be nice for us how still are in the process of doing the same mods.

Good Luck
