Default Finally back from the Dyno!!

For the followers, I pull 580hp/542tq. @14.5 psi. I'm pretty happy with those numbers, but the car is still idleing like Sh*t. The car was spinning on the rollers with two mechanics in the trunk. Didn't help. They said for sure over 600hp, but 580 is on the sheets, so thats what it is. I'll do a rubber swap in the future and see if we can hit 6.

I still bave the stock 96 Bheads on it. I didnt tear them down, get them cleaned, valve job. Stock cams. I have no idea what the idleing problems are from. Its awful
The car literally wont stay running without pedal at first start up. And if you depress the clutch at over 1900rpms. It shuts off. 98% of the time. I paid for this to be fixed....it has not been. Not happy. They checked for vaccuum leaks to no avail. And tuned it over and over. Replaced idle air. Etc. They have no idea. And this car is embarrassing to drive.
