I'm not real sure on your tuning situation but I can't express the need for hands on tuning when cars are modded to this extent. I have done the data log thing going back and fourth with emails and it's just a PITA. Cars need to be tuned on the dyno then need to be tested on the street. When running a pwr adder things go wrong so very fast.
Good luck and sorry for the loss.
