ok so it was hard enough to find a gauge cluster that went above 160 mph but I think I found a saleen s302 face plate I'm not sure yet if it's for the s197 model but if it defiantly did fit can an in tune diablo tuner recalibrate it or would I need to go to a tune shop because I'm using the factory cluster just a different face?

You could technically play around with rear gears and tire revolutions per mile to get the MPH to read relatively accurately, but then your odometer would be off.
I bought a Saleen 200 MPH gauge face and sent it and my cluster back to the company that does the Saleen modifications. I think it was $150 to reprogram the gauge cluster and install the faceplate. I can give you the contact info over PM if you're interested in going that route.

Do you intend on going faster than 140 MPH?

101btp

yes why yes I do

changing the gauges to read a different MPH would cause a need for a recalibration

101btp

lol yeah I know that's what I was asking about but I already got the info to do it

To the OP and not Ford-a-tude:

I hope to hell, that you have changed out the driveshaft to a 1 piece, or you might just get the surprise of your life with speeds over 120.

Jwood562

That would be bad news

I'm pretty sure he's doing a V8 swap.

lol yeah the only thing im keeping is the body doing a v8 swap rear end swap k member swap subframe connectors suspension swap and carbon fiber driveshaft, and yeah I have seen the 4.0's shaft's snap really quick with people going 120 have seen um go 135 too and then instantly go but thank's for the concern!
