I'm going to do the gears so it also has to recalibrate speed.

Here's my major concern though.

When I bought my mustang it was being sold with a Diablo tuner, but I forgot to grab the tuner off the guy and when I went back he said he had lost it (but I think they sold it...anyway).

I think there's already a tune on my car (though I have no idea what it is).

But here's my concern: The way I understand it a tuner is supposed download your car's stock tune to the tuner....well my stock tune is lost in that diablo tuner somewhere.

Am I able to simply buy a new, say SVT tuner, and start over from stratch with whatever tune is currently on the car? I'm sure I'm probably getting some better performance, but I have no idea what it's rated for (mpg or hp/octane) and I'll be needing the speed calibration anyway.

What do you all think???

SCT tuner you mean (you said SVT lol).
as far is i know, if you buy a brand new tuner, it will take whatever tune is currently loaded and save it, then swap out that tune with whatever new tune you have. however, i cannot confirm that, as i myself am just running a burned diablo chip from the guy that did my dyno tune.

best bang for the buck tuner is megasquirt but that requires eliminating the stock computer and running new wires for everything lol.

Ok well let me make some revisions...I saw alot of people like ...SCT
What I'm looking for is a handheld that connects under the dash.

SON1C

sct x3 for sure.

SCT tuner for sure. I just bought one to replace my Diablosport. Buy it from American Muscle and you get free Bama tunes for life!
