Blowers on,trans is shifting funny!!!! y

No its not a blown trans. Lol That would be easy. Well I just put my D1 on my 98 GT. All it has is exhaust and blower. When i give it gas 1/4 throttle up to 3k the idle seems to stick and the trans seems like its stalling then moves again.

I'm thinking that it can be 2 things:
1-Need a bigger gear then a stock 308 gear?
2-Might need to change the shift pressure in the trans with my tuner?

What do you guys think?
 
Didnt do it before i got the blower on and only does it going into 2nd gear. I'll still haven't got it tuned but i might tune it with my friends. We have a Mustang Dyno, and its pretty mustang a stock car with a blower. So will just watch the a/f and see how much fuel,spark we'll give it.
 
You say you havent got a tune??? Surely you did some kind of tune with the blower. You got a chip/tuner with it right?

I'd say the problem is probably the tune.
 
Yea its for sure in the tune. Im trying to see if i can data log whats going on with this diablo. I tried gettin in contact with one of the diablo sellings but he hasn't got back to me. Soon as i get the data log i'll be able to tune it. I'm going to try a street tune if its not running right i'm going to put it on our dyno.

BTW never had a auto sports car. Lol I'm putting a TKO in soon. If i wanna really go fast then i'll put a TH400 trans in.
