If you put a 4.10 in the car, does it still need a tune?

I have a PP2 which has smaller diameter tires which effectively increases the final drive ratio. The stock 3.73 acts like a 3.94 gear. If I put the 4.10 (which, I think will act like a 4.3 - ish gear), will I need a tune?

all the best with your 4.88

Don't think there's any issues if your not changing it in a Bullitt.

That's all I've had issures with, or heard others say.

@L0566Bullitt, have you had an opportunity to take the Bullitt to the drag strip on the 4:88s and sticky tires? Would love to hear how it performs and what gear/speed you trap at.

Unfortunately I have not. With work I really never have any free time and it sits in the driveway 98% of time except when I drive it to church on Sundays.
