Hey guys, just a general tuning question.
Basically the car has been tuned many years ago to run the GT2876R that was on my car. It ran beautifully, clean response and no detonation.
That turbo is now off the car and a GT35R is repacing the old turbo.
Will i need to get it retuned? I will be running the same boost as before (8psi) and the only thing changing is the turbo size.
My query is that with the haltech, and the sensors that it runs, TPS, O2, manifold pressure, air temp, water temp, timing etc - will the computers current tune be able to justify/compensate for the slight change in air density that the new turbo will be producing?
I know I will probably need a tune, but i thought running the same boost levels, the computer will be able to adapt to the 'new' air being produced.
Thanks all in advance.
