performabuilt rules
#1
im not guna get into all of the details but i called atleast 15 times trying to pinopint a problem. customer service picked up on saturday afternoon and i didnt call once without a pick up. performabuilt told me exactly how to test the converter, and how to determine whether the pcm was telling the transmission to shift without hooking up HP tuners. in the end we got the problem solved and i have overdrive again! they pinpointed the problem over the phone and i now have overdrive again!
