Default Ran like **** tonight...

Ran a 14.1@97 and a 14.4@96... cut 2.2s each time. I get a nasty *** vibration through the dash and center console. Thought it was the tranny mount, but it isn't. She's on a stock PCM but misses like holy hell all the time. What could be wrong? I run around 220-240 degrees thanks to waiting with the car on in the staging lane, but still should be running much better than this... advice, please.

they'll be brought way down when I do the intercooler install in a few months. She's running way too poorly to just have temp probs though. I'm trapping 3-4mph lower than a stock OBDI LT1 does.

Could the heat and boost be creating so much knock that the computer doesn't compensate correctly?

it may be... the car needs a tune so bad, it will be accomplished within a week. I'm going to see how she runs then, and after the intercooler... hopefully it will be cleared up by then. If not, I'll have to tear her apart and try to find out what the problem is...

Does the lt1 habe a MAS or a MAP. IF it has the map sensor, it could be smoked or not setup to handle the SC. I drove 2 supercharged lt1's and 1 ran like total dogshit(camaro) and the other ran awesome(corvette). They blowers and such were the same it just came down to the tune.
