i am thinking about perchasing a tuner, such as the diablosport, and i was wondering what it can do. right now i am running a O/R X-pipe, and i heard that i can tell the computer to not worry about the catalyst system. thanks

What he said.

Seriously, I have one and it is great!
Coupled with my 4.10's I gained almost 8 tenths with it.

Yes, But that says 15-20HP? Is that on a stock mustang? Slightly modified? Anyone seen true gains from this alone?

In all honesty I really didnt notice much SOTP gains from my diablo. The biggest benefit to me is being able to adjust for gears, tires, turn of Trac Control, turn off rear O2s, shift points of ATs, plus the performance gain albeit a small one. Worth it to me.

I'd expect about 5HP kick on a stock, 10 on a mildly modded Stang.

when you say slightly modified stang, what would that mean? right now i just have the x-pipe, but gears are on the way (3:73's) and a shifter. what else should i do to make it perform the best. i am planning on getting U/D pullys as well. thanks

I am thinking mine is slightly modified. So, if you calculate my modifications what kind of gains are expected?

I was not aware that you could turn off traction control, disable o2 sensors, and recalculate for gearing. I guess for the cost of MIL's/Speedcal and not having to turn traction control off everytime as well as the many other features. It might of been worth the extra couple of bucks to get one.

If you have an automatic trans it will reset all shift points to optimum spots in the powerband, providing you get a custom burn or a dyno tune. A off the shelf chip will only go so far.

I THINK you can fix that problem. Don't hold me to that though. I know you can definitely adjust the lean/richness, but to what extend I am not sure. I have not messed with that much.

I think it is definitely worth it. It is great having Traction control off when I turn the car on, being able to up the shift points a tad, adjust for the gear ratio when I get the 4.10's installed, and various other stuff. It will do a lot more, but for me personally, I would probably have someone who knows more about what they are doing work with stuff like the air/fuel ratios and spark advance. Maybe if I get brave after I learn more about it myself.

If you are planning on modding your car with gears, it would be useful and should knock off some of the price for install because you'll be programming for the gears, not the shop. I don't really know how much that will save you. I will find out how much it saves me soon. I might post it when I do.

It's hard to say if it's worth around $380 for the thing. That's what I got mine for after shipping. Just read a lot about what it can do, and decide if it's worth the money for you or if some other mod would fit your needs more. I can tell you one thing - don't expect 15 or 20 extra HP. It's really not for that. Maybe a professional tuner on a more modified car.

My main concern right now is to tighten up my auto trans. A shift kit or Jerry mod is cheaper but that's pretty permanent and my warranty goes out the door immediately.

If I go with the programmer route, I'll spend about $400 on the programmer...

minus $60 for a Speedcal that I won't need when I get 4.10 gears
minus $40 for the MIL Eliminators that I won't need when I get an off road H pipe
minus $150 for a timing adjuster that I won't have to buy and install

So, the real cost of the programmer is only about $150, and everything is reversible in 5 minutes.
