Better yet, buy H PTuners or EFI Live and learn how to do it yourself. If you have any sort of grasp on fuel injection, you'll have no problem learning how to tune your own vehicle with all the resouces out there. Especially with the minimal mods you have right now. That's what I did and have never looked back. Started out with a stock vehicle, added converter, then nitrous, then cam, etc. I wouldn't pay anyone 300-600 bucks for something I can do on my own with an hour or two of my own time on a weekend afternoon. Start to finish after cam, converter, headers, gears in under 2 hours except for time on the dyno and base running airflow scan from a cold start.

Well good news is selling the diablo will put money back in your pocket and it will still get to 90 just as fast. Then you can order a custom tune, and get to 90 faster and also have a little bit more power beyond 90.

After that improvement you can look into cam, intake, exhaust, turbo, and millions of other options to make more power.

Well the mail order tune will get u a little closer but they really cant tune for ur location, but it a bit better than nothing. Just have to make sure that the shop doesnt lock ur computer . My 4.8 stock with cold air and exhaust kinda maxed out at 80 and takes a while to get up to 90+. lol 5.3 swap time! lol

Get a live tune or mail order tune. You can wipe yr *** with that hand held piece of crap. The only thing there good for is. Paper weight just like a throttle body space.

I love how you guys are baggin on this tuner. The diablo sport is a completely different animal than hyperjunk or superdips. Now, in order to make it useful a custom tune must be emailed in order to make it useful. It can be used with custom tunes as a loading device which is very convenient. At one point Nelson performance sold this tuner. They have stopped I believe, but it's not the trash many of you are implying. Moral of the story not all handhelds are created equal.
