I have a 97' A4 with an APR chip, and a new KO4 turbo. The previous owner screwed with the KO3, so it broke. My dad got it replaced witha KO4. Im trying to geta grasp on the power increase, can anyone either tell me the approx hp/torque of my car, or give me a comparison of KO3-KO4 in terms of power.
Thanks

 

None. You will need to get K04 specific programming to get anymore power. That would get you approx 30 more HP. Your car is approx 195-200 HP now. Moving up to the KO4 giac file, will get you in the range of 235 HP.

 

so I would have to get a new chip for it to function any better than the Ko3? If so, would I geta B6 chip then?

 

Umm, no. Your car is a B5. B6 = 2001+

 

well how can I get the power from the ko4. You said I need I need ko4 specific programming, could I update my apr chip?

or, can my car be programmed to use the k04, and where and what price can it be done for?

 

get the GIAC programming for a K04, you'll need new injectors and an aftermarket DV to run the new boost and turbo, an exhaust helps with a FMIC and intake so the turbo doesn't overheat

 

Im almost positive a DV was installed with the chip, but how much will injectors run me?

I plan on gettign borla exhaust pretty soon, hopefully in feburary or march.

Currently I have the ko4 and an apr chip in there, does the ko4 just run at less than max efficiency, or am I hurting the turbo?

 

The K04 will run safely on the APR programming, it just runs like a chipped K03

 

i ran my k04 on GIAC k03 software for 6 months without any problems, like david said it just feels like a chipped k03, get the pc16 and you'll feel a difference

 

Whats a pc16? Is it an ecu update/upgrade, or soemthign I coudl add onto my APR chip, or will I have to get a GIAC? Sorry, Im really new to the whole Audi deal, and Ims till learning parts, etc.

Whats are the minimum reqs for getting power out of the ko4 while keepign the car runnign healthy? I plan on getting an exhaust as soon as I can.
