Hey Im am thinking of swapping over my Fathers truck over to tpi this summer and was wondering what is needed in order to keep the computer happy with a TH400 Tranny?? We have most of the parts already and I have just gotten into chip tuning on my mpfi converted tbi. Not the edelbrock system. Holley manifold and fuel rails with larger tbi as a throttle body. Runs good so far. I know that this isnt a truck site but you guys seem to beable to answer most questions/and have alot of experiance with this stuff. Is it as simple as just putting a vss on the th400 and if so how would you hook it up?? THanks for any thoughts.
