You might want to keep the Airforce until you get the xcal2 and try that combo...mike adjusts for the parameters in the computer that cause the CELs....your engine, tranny, and computer just doesnt know what to do with an intake unless you are tuned for it....i guarentee you wont want to get rid of the airforce once you get tuned....should have been tuned before you got the intake.....


a crock? not nearly, the roar, needless to say the performace gain from the exhaust, intake and xcal2 combo...is WELL worth the money spent...haven't came across a hemi yet that could hang with me... ..your decision...goodluck

 

Are you running the 88 octane tune or higher to avoid the CEL? I know the Diablo tuner allows you to tune the fuel mapping which would help avoid the CEL. From what I've heard, the Xcal2 comes with preset fuel maps, which at the higher octanes may avoid the CEL.

 

Yup, 91 premium octane tune...it is so awesome i am at a loss for words
