hmmm ya i hopped on the mustang dyno today and with my mods in sig i only hit 260 whp 236 tq....... only maxing at 17 psi the car was running rich too so next thing is to toss on a MBC pin it to 20 and check it again and finally have it tuned on a dyno to get things right.......

you put his boost solenoid on or a boost controller?
how did you crank a MBC to stock position and it hit 20psi like it did before you put it to stock position..... elaborate on that a little more please

sounds like your car is back to normal by the look of your boost and do you run a MBC now or before????

 

I put his manual boost controller on and we turned the hex screw all the way down, which is supposed to be similar to stock solenoid settings. The car was hitting around 20 psi and slowly falling down. I don't mind driving around on 10psi for now, because I'm still waiting for cams, head studs, and then right before I go get it tuned I'll slap the boost controller on, so that way I'm not tempted to do anything stupid on an untuned car.

 

heh dave at buschur says it looks like im running perfect from my dyno results since it was only at 17psi...... said if i push it to 20-23 it should put me where i should be..... just feels wierd like, it used to bang gears when i'd WOT and shift hard now i cant if it try.....
