Can anyone help with this? I just called Anders at EVO Motorsports and while he said they have both programs available, he didn't know off the top of his head what the differences were between them. He graciously offered to call Garrett and find out, but since the holidays are upon us and I'd like to get the chip, injectors, fpr, etc. installed this weekend, I thought I'd ask around here since it may be a few days before he can get an answer...

Same file. 3 bar 310cc injectors, K04, 93+ octane...

Anders can call me if he has questions.

What is your fuel pressure at when you get those readings?

Looks like your fuel trim readings are good when you get the .85 02 sensor readings. Dont worry so much about the timing being pulled back since most all chips do that anyway at some point.


Have you done a compression check of all the cylinders? Could be that the compression is higher in cylinder 1 or the fact that the voltage sensor readings are just not as high in that cylinder.

with the vag. Testing 02 readings vs a wide band shows that .85 is in the 12:1-12.5:1 range while .90 in around the low 10:1 and into the high 9:1 which is where the car will start to studder because its too rich.

Those chips did have problems with being too rich in the midrange which could be why the power below is not all that great. But then the power of a K04 should start right around 3k.


Both chips could be for 310cc injectors but might but the lower boost chip should be for a stock IC while the higher boost one should be for a FMIC.

Just try not to push it below .82 which is where it really starts to get too lean.
