getting a gt sct ?

Do you mean tuning the setup on a dyno? Either way, don't expect any more than 7-10 hp over stock, closer to 7. It's still an honest 7 or so horsepower though.

There aren't many dyno charts for this setup since it is considered so close to stock.
 
I made 233 at the wheels with a catback and SCT chip (really only got the chip to correct the 3.73 gearing). Prior to the chip, it made 228.
I haven't dynoed or retuned with the Accufab setup, but at 3K RPMS, it really wakes up and pulls better than ever to redline.
(Note - I've sinced switched to a Predator tuner)
