I just switched from my zzp 1.0 tune to overkill pcm and i am getting same mpg a bit higher temps on coolant and transmission as well as 2 to 5 knock cruising... Much more knock than zzps tune... My car also sounds a bit funnier when first accelerating before boost. I already sent my zzp tune to overkill im a bit dissapointed and dont know what to do.
