It was not detonation. Simply a little interference in the pickup on the dyno. It was cutting out that day and this was the only run with a solid line where the other couple of runs had breaks where signal was lost

SWEET98SS, drivability is remarkably smooth, even in 1st gear off of idle. I believe the car is tuned extremely well and it had a good amount of tuning time to get it just right, I think. Forum member 'chevyls10' is the gentleman who tuned the car so maybe he can chime in to verify that. Not concidering the sound and lope, but just from the drivability alone, I think most couldn't even tell it wasn't stock.
And another thing which is a bonus, the car gets about 33mpg highway, 22-23mpg average. The fuel mileage if I stay out of the throttle is actually slightly better then it was stock.
