Dyno tune it and call it a day. I had a lot of problems w/ my SCT device so I'm just going to take it in and have it tuned on the dyno...

under 300? try diablo predator on ebay.... maybe even a sct. a tuner under 300 is going to be used.

+1 on Xcal2 - that's what I use... a lot of diablo users say the tune doesn't help unless you have mods - but my Xcal2 helps regardless just has more of an effect if the car as you put more mods on your car. Xcal2's normally goin to fall in between 350-400... but imo it's worth it. So many options!

Hey bro.. I would recommend an SCT X Cal 2 for the fact that SCT software is the choice of most of the top tuners in the country and will give you a lot more use than a chip.

The Xcal can hold several tunes and allow you to make changes to them consistant to mods you may do in the future as well as the capability to datalog to see your cars vital statistics.

Chips are old school. The new style is handheld programmers which are like having tuning software.

Give us a call and I'll sort you out on a great deal on an X cal 2.

Thanks, Jared

How much horsepower will i see from a tuner with a cat back and intake? Is timing the only thing I can do to improve performance safely?
