I've got a 98 hatch with a d16y8 vitara build. Will be making around 400 wheel. The car is going to be tuned on Neptune and i would like to do boost by gear. the goal is a 10.99. I know i will have the power its just a matter of putting the power to the ground and driving the car. So my question is, after the car is dyno tuned and the boost by gear is all set, when i blow a trans and find another $70 marketplace replacement and its got slightly different gear ratios does that mean the car will need re tuned? Excuse my ignorance this is my first build and i would ask the tuner but he is hard to get a hold of.
