I have just recently finished tuning it for 15 pounds of boost, but it's pretty ridiculous on street tires. It spins in 4th gear, so it either needs drag radials or drop the boost back down.
This is an awesome car that was built by DDNSPIDER (Nick), who is a well known forum member on here. He also did a good job putting the original ad together when he put it up for sale last year, so I've pasted it below and updated it with the recent things that I've done to it. Also, I have a folder of receipts and paperwork for the car.
"If you're looking for a front to back fully built Trans Am with provenance, this is your car. It has been on the cover of GM High-Tech Performance as well as High Performance Pontiac and "How to Turbocharge the LS1 engine". This is a completely built 1998 Seabring Silver Turbo Trans Am I've only had to do oil changes and spark plugs since I finished modding it. It was built with daily driver reliability and was my daily driver at one point. Now I drive it on the weekend if I have time. I'm running about 8psi on the 78 mm turbo, so it's not even working hard. Car has been 10.6 @132 mph in the 1/4 mile driving to and from the track with a 6-speed and zero weight reduction on 8psi and 93 octane. Car is on the fastest 6-speed list on this site. Has full A/C system and full interior which is in very good condition. I can hop in the car whenever I want and it fires up immediately and drives like stock until you push the gas pedal. It's fairly quiet (full axle back exhaust) considering the mods, but screams when in boost. With the exhaust cut out open it's literally the best sound of ever heard from a car. I don't need to sell it, so don't bother lowballing. This is a proven car, not just someone who finished their car and stating it should make XXXhp or SHOULD run XX.XX ET."

Drove it to the office and took my boss for a ride
and scared the fool out of him (in a good way)! He has a 2012 Grand Sport Vette, but now he's got the itch and I've talked him into buying a C7 Z06!

The last couple times I fired up the car I was hearing a squeak under the hood. Finally figured out it was the AC belt tensioner. New belt tensioner installed and squeak is gone. She is ready for purchase.
