STS dyno on my stock 140,000 motor yesterday
I finally got a dyno yesterday to see how much power the old motor was puttin down...I made a few pulls and here are 3 of them..the wideband was being recorded on a seperate laptop. The pulls in order from lowest to highest were 4.5psi, 5.5psi and 6.6psi all on 91 octane...I am new to tuning and this was off my street tune over the past 2 weeks...the timing was at 13 degrees and the a/f was at 11.1 all the way across until about 5300 then it drops to 10.9-10.7. The car kept making more power each run but we had end the dyno session early because they were having problems logging wideband and it was wasting my laptop battery power.....Since the dyno I have got my gain settings right(boost controller) and my start boost so I am getting full boost faster and I plan on getting an off road y-pipe this week. Im going to dyno again wednesday and run more timing (14-17) and higher boost(7-10psi). I can boost 10psi safely with just the intercooler and I havent run meth yet. Also thanks to Blackbird and Zombie for helping me out with tuning advice and help on my setup.

I ended up sending back the boost controller to greddy and then when I got it back just reinstalled it and it worked. At the dyno I was running stock gain settings and 0 start boost which was hurting spool up.

...and what boost controller are you running. I saw something about Greddy, but which model? Nevermind... It's in the sig. Congrats on the setup, glad things are moving forward with the project.

I'm getting full boost by 3600-3800 with the gain settings at 18% and start boost at 12. I'll be going to the track wednesday night after my next dyno and see what it does at the track.

check for leaks both in the exhaust and then going from the turbo to the throttle body, I believe it should spool quicker than that.
I have to do this too as mine is spooling where yours is and I am pretty sure that is not right, I know before I changed some things around I saw a full 5 psi by 3100 on the dyno.
