Well, got back from track last night. My times improved by half a second or so but still not in the 13's. I ran consistent 14.15's to 14.2's.
Here's my best slip:
60' 2.176
1/8 9.246 at 78mph
1/4 14.151 at 100mph
My launches were decent, I didn't bog nor light up the tires, and I shifted at 6K. I'm certain I didn't let off early. Given all that info, and the notion that my 60's aren't that bad, it seems like this engine isn't pulling hard enough the faster I go (3rd gear seems slow, in fact I hardly have to put it in 4th to get to the finish).
I think I'm going to check my fuel pressure today. Might have a burnt impeller, I know the guy before me said he ran it out of gas not long before he sold it to me.
Off topic, I did make it to semifinals (4 F-bodies in the semis) and lost to a LS1 Z28 due to a break out of .009. Damn I wanted that trophy!

I took to Autozone today to have scanned. It passed, no codes.

Did you clean your maf? K&N oil can dirty up that thing. Also since he ran it out of gas it could have sucked up crap and plugged an injector. Try some seafoam in your tank. I don't remember, but did you check compression?
Good luck, something isn't right.

have you cried in frustration? i probably would.
with all that new stuff in the car it should act like new, the only thing left to think of is the injectors, MAF (which was one of my buddies problems), or fuel pump may be really slow and getting no pressure.
I would go to a speed shop and get it dyno tuned. if it didnt make the HP they expected they could prolly tell you the problem.
try seafoam first and foremost. you will definately be able to FEEL when the problem is fixed.
good luck

What Tires and size do you have on the back?

I cleaned the MAF w/ non chlorine brake clean as well as ran a can seafoam thru tank and half a can thru brake booster, and I picked up a tenth - 14.05. Car still is down on power. 2 other stock f bodies at track tonite and both were low 13's. Both were 02's so have the LS6 intake (I doubt if that can account for half a second or more). My 60's were at or better than theirs but I'm still only trapping 100mph and barely into 4th gear. My best run tonite was actually a 14.001.

Did you put your gears in? Or are you assuming it has them? A regular M6 TA and an M6 WS6 TA both have 3.42's in the back.
Earlier you were asked if you let off before the end, you said "anything is possible"
Did you or didnt you?
