i got the car dyno'd yesterday, and my a/f ratio was rich in the mid rpm's


this is on a dynodynamics dyno that dyno'd a B6 s4 with full milltek at 235 whp.

so the low hp doesnt bother me, i am just wondering what others a/f ratios looked like.

i am pretty sure my N75 is shot, the boost was jumping like crazy

Check for boost leaks I used to have trouble with boost surging. I found 3 boost leaks after doing a pressure test.
