hi guys, this week i change my turbo from garrett .63/.50 to a precision 3431E
.63/.60 the car was making 333whp/241wtq @ 16psi. Now set to 14psi the car is running way better in 1rst and 2nd but when i put 3rd the car slow a little (one second) and suddenly start smoke the tires again. If i make a pull
in 3erd at 4.8k or 5k it smoke the tires, the issue it's shifting from 2nd. My
tune is in crome pro the 14.7psi row it's been always at 15.0* I know my
problem is with fueling the car run a tad rich but i keep lowering the fuel in the b13 and b14 row but the problem still. Any help be apreciate.

P.S. I always do street tune with ostrich an when i feelt it strong i left here.
in 3 years with the car and four engines i only hit one time the dyno.

thanks
carlos
