I'm hoping some can tell me what HP gain I could expect from a 2.94 that is on the Cobra I bought. and are the Diablotuners worth the money???
Thank You again :thumbsup:

Diablo and SCT tuners are worth the money yes. BUT, the real question is WHO you get to tune with the software. Don't use one of those "box-tunes" that come with the tuners, get a custom dyno tune from a reputable shop.
There are some shops that offer mail-order tunes that will work with you and the dyno facility that you are using to make sure you have a safe and powerful tune (ATS - Amazon Racing)

For each lb of boost, expect around 15 to 20rwhp

So depending on your other supporting mods and your tune I would guess that your car is making 5-6 more pounds of boost than stock, so to the wheels 440-460rwhp depending *GREATLY* on the tune.

Good luck with it and I would highly recommend getting your car on a dyno to get the a/f readings, plus you'll get your hp numbers which is always a bonus. :D

Hope that helps.

If you don't mind travaling to the Detroit area.. Take it to Alternative Automotive and have Lidio tune it for you. He has the dyno and uses SCT chips.
He did my 04 and I couldn't be happier.
