for anyone considering a mail order PCM. Overkill is the only true option right now. yes there are others but they are not nearly as good. I have been tuning this platform since 2005. I have seen PCM files from all vendors. ZZP, Intense, Overkill, ect. by far Overkill's PCM's make the rest look silly. for someone wanting the very best tune for their vehicle this is the recipe i suggest:
1) buy PCM from overkill
2) have experienced local tuner perform MAF tune to adjust fuel trims.
3) enjoy!

or if Overkill will let you send him data logs to adjust your tune from. then you can skip the local tune.
I have worked in customer service for far too long and agree Service is key... but we are not talking about someone who is selling coffee mugs here. tuning is an art form. his work is worth the wait.

When I do in car tuning for members, there are many adjustments that I change. With Overkill's pcms that list is very short compared to other vendors.
