Both of you had stock trannys and at the time no money for built tranny? I hope you are talking about him because you dont need the built tranny to run +310 and +325 tunes.. Alot of guys are running the +345 tune as a daily driver and racing too but it will start to take a toll on the TS after a while
I just preffered to play it safe until i have the money to do it right. Not saying you cant run them. Just what i wanted to do.
