Q : WHAT THINGS SHOULD I CHANGE IN THE TUNE ???

[zo6 speed]

anyone ??

i know i have to change A/F ratio , timing what else ??

[ktoonsez]

Yes on both. The bigger cam will probably need more timing in the idle areas to remain smooth. AFR, you will need to retune your MAF and or VE tables to account for the different needs of the cam.

[DSteck]

Startup Airflow, idle parameters, timing maps, MAF calibration and VE calibration, and possibly P0300 criteria if the cam is generating noise.
