I have a turbo s2k and I'm running a aem 1052. The tune overall has been good but I feel it's running a bit rich during partial throttle when I'm under 80. On idle in at 14.2 give or take and driving fluctuates between 13.8-14.5. I know stock, it's always around 14.7 and goes from 15.2 back to 14.7. I know I'm off by just a but is there a way I can just increase the partial throttle setting under 5k rpms. If anything, if the aem has a set a/f ratio I can choose, would it be a problem increasing it a bit?

Thanks,

 

get it tuned on the dyno, there's no short cut for good tuning.

it's easy for any tuner to do a WOT tune(one position) but partial throttle tune on the dyno will give you much better real world driveability.

sorry, can't give you a simple answer, start calling up local tuner.

Take advantage of the AEM unit, it's a far better system than the old day with sh-tty FMU and 5th injection guesstimate tune
