I've had my eye on the Diablo for a while now and expect to order one by the end of this coming up week. I need a chip to not only calibrate for rear end gear changes but also for tire size changes. I went from the stock wheel/tire setup to some 275/45R20 eagle gt IIs and the stock 3.55 to a 4.10.

Can both the Superchip and Diablo computer chip correct for rear end gear changes and tire size changes? I know the Diablo page says it can, but it never hurts to double check.

And while I'm typing, I'd like some opinions on which chip would be better for my truck. Or would the Superchips MicroTuner be a better value? My truck is a 1997 4.6L F150 2wd.

Thanks in advance for any help and suggestions.

 

Alright, ignore the previous post and just tell me what would be best for my 1997 F150 with the 4.6L V8 with a 4.10 rear end.

Superchips Tuner OR Diablo sport chip?
