I bought my 07 ram hemi used, and it already had a flowmaster exhaust and a mopar intake installed on it so im wondering if it has some kind of chip or computer done to it as well.

Im just curious because the truck pulls really hard, its a reg cab short bed with the hemi so not much weight, and it seems faster than my moms 05 grand cherokee wit the hemi.

Also if it doesn't have a chip what would be the best to get. On my 97 silverado i had a westers computer tune done to it, and it seemed to work well>?

 

Everyone always thinks their truck pulls harder than everyone elses!

Anyways, I doubt you have a chip in your truck.
I just bought a Diablo Predator as it has the MDS disable option! Love it. It shifts very smooth compared to other I have heard of like Superchips.
A tuner doesn't add all kinds of power, but gives you an additional edge plus some hp. I stuck the 91oct tune with MDS disable and am happy. I only bought it for the MDS disable
Superchips does have an update for the mds disable as well now, but I heard their tuners have horrible shift patterns, plus their tuners are set and you can never custom tune anything or modify anything like diablo has available

 

Most chip manufacturers do not leave a signature so the dealer has no way of knowing if the truck has been tuned. I suppose you could take your truck to the dealership and ask them to re-program your PCM - may do it for a cost though. Then see if there's a difference when driving. However, if you have a programmer, you would want to return your truck to stock first.
