Hello everyone, Well today I finally got the stage 1 in the mail from SPG9 and installed it into the car soon afterwards. Before this I was simply running the stock unit that I had turned the pots a little on. It was about 75 degrees here this afternoon and that may have affected my initial impressions. I then ran the car later in the evening to see if it did a little better. It did and I was like yeah that's cool, not sure if it was much better than what I already had unless I'm missing something. I mean before this upgrade I could easly get to where the red begins(12-13 psi?). Now it does go a little further with the stage 1 APC, and only a little. About an hour ago, I took the car up on I-75 which is just 5 minutes from my house. Upon getting the on ramp I decided to push it as far as I thought it would go, not WOT though. I held 3rd, 4th, and 5th gears until about 4000 rpms each. I noticed that the boost gauge (stock) would now go to about 1/8 inch into the red and the car does seem to pull a bit harder. I finally decided that I might have gotten an increase of about 3-4 psi perhaps? I was really expecting a little more however. Also because I was already running a tweaked APC, that could have made the upgrade seem less to me. I really don't know. Only that I expected more that's all. My car should be pulling like a Pitbull on crack period. Maybe something else needs tweaking to make it perform better? what else should I be looking at to get the most or to get it just right? The car in question is my 1988 9000T Airflow, with 116k on it's clock. Upgrades now look as follows:

Stage#1 APC
2.8 bar FPR
Blue Series Injectors (#27?)
Magnecore Wires
20 PSI BOV
K&N Cone Filter
BB T-Body (next week?)

Thanks guys, Phil
