Message Well, looking over your chart there. Start will the basic's. Don't get all stressed out until you've search and found the answer.

60': 2.356
330:6.324
1/8: 9.463
MPH: 74.63
1000': 12.268
1/4: 14.650
MPH: 94.05

Ok, looking by this, did the tires spin much off the line. That's a big 60ft for an Auto Z. What where you launching at? At anytime on the runs, did you see the Rpm's fly up fast, yet the car was not moving full force, as if the tranny was slipping? Did you put those colder plugs in? You might want to keep the stock temp ones until you increase the boost. If you never changed them, then pull them, look at the tips, that'll give you an idea what may be happening. That rough idle down low is plugs most of the time.

Race gas or pump? I take it pump, cause race technically wouldn't have done anything for you on stock boost levels and no adjustments ( raised ).

Remember stock auto tt's are already 20less Hp than manual types. So with a fully stock car at 3500+you, running 9psi with some 238rwhp ( on a prefect compression ), with your known boost leak, meaning your like running safety boost levels now of 7-8psi your right in there and the car is fine for the boost leak problem.

Do a boost leak test, very easy. Check the plugs, if #6, go back to number #5's, check the gap, bad gaps make them miss on the top end and idle rough on the low end. What octane where you running? What RPM's did you shift from 1,2 and D? Was the car building boost on the line as you power braked? Lot of questions I know, but it's for all to get a better understanding of what we can't see or hear. Run any octane fuel system cleaners threw the car yet since getting it? Main, thing now is just get the car running or know that it's running what it should be ( 9+psi ).

STAGE V++++
Going to XV+ and beyond :)

Yellow Z STAGE II
Going to XI+
