I wouldnt feel comfortable driving a car that had a cam added and was untuned- Im sure a dyno tune will make quite a bit of difference. On my last car 98 trans am auto with bolt ons- the dyno tune after i did the mods was the best/most seat of pants difference of anything i'd done to it.

Hopefully you have access to a good tuner in your area that actually knows LS engines. Unfortunately for me, there isn't anyone in my area. They will dyno it, but to have someone actually spend the time to dial it in and have it run well on the street and also at WOT is far and few. For these reasons I decided to buy HPTuners and learn how to do it myself. No one will dedicate the time to your ride like you will. And if you plan on keeping the car for a long time, it will be money well invested. Just take a look at their website and read the forums to see how many times a dyno tune left someone short changed.

im buying a cammed rs off of a guy, he had a 01 trans am and did just about the same mods on it u did to yours. gained 35 rwhp. had dyno sheets to back it up. and gained some mpg too. definitely worth doing

you can buy HP and check to see if it has the stock tune in it. or pull off the rear 02 sensor and see if the SES light comes on...if it doesnt the code has probably been deleted in tuning. not really worth betting on though. rod bolts and ARP on the heads, and strap some juice to the thing. then tune it.

The driveability should significantly go up if its still on the stock tune. Your also probably not getting the most out of your mods with the stock tune. I just have a few bolt-ons and i got a tune and its much smoother and driveability is much better. Not to mention you can make sure engine is running safely.

well the specs of the cam say 6600 rpm peak
Peak power also has to do with your heads and intake, and the durability of other components down the line. The previous owner probably kept the 6000 rpm limit because of the stock ls1 intake/heads and for longetivity of the rods and transmission.
You should have a local guy scan your car or read your tune and compare it to a stock tune and see if anything was changed.
