Okay here's the deal my buddy wants 373 gears like i put in my mark Viii. But unlike me he has a 3.07 ratio not a 3.27 as i did i in fact i needed no tune to do it. My question is this do you think he can go to 373's with out a tune? I say yes i doubt Lincoln used a different tune for a 307 vs a 327 thoughts? As always thanks in advance for your help in this matter!:thumbsup:
 
As a guy who's done a few gear swaps, I will say that "can" and "should" are two different things here.

He, like you, might be able to get away with doing the swap without a tune. But he shouldn't. Yes the car may go down the road but it probably won't be at it's full potential.
