Wow. You drop .2 off your 60' and have no gain on your ET, meanwhile dropping 4mph off your trap. An unbelievable bad result. The only things I can think of are ... how did the DA's compare between the two runs? Was it a lot more hot and humid this time? Did the tranny shift the same? Air, fuel, spark delivery all A-ok? - anything from a dirty maf to a bad plug could affect it. If everything else is good, then the most obvious choice is that converter is horribly inefficient and killing your top end.

forgot to add that i added nitto 555's on the back and switch from a predator to hptuners. on hptuners, i killed the torque managment, added the spark table from predator and adjusted the PE a little.

Take it from me it was the weather.
You lost 4MPH ,but your 60ft came down that is the weather.
My Car was stock, and the best time in good weather was a 12.96
After I put a 3200 in it I went down to a 12.53. With nothing else done to it.

the previous was in the spring of this year and if i remeber it wasnt really hot or cold.
on the run with the stall, it was overcast and about to rain and probally warmer by at least 5-10 degree's

doesn't the humity go up, and the pressure go down right before it rains? that would effect the DA, and make it seam like you were running 2000 ft higher than you are. Cuz ya know, ya gotta be a mini-meterologist to be a competeative bracket racer.

I guarantee you it's the weather. Before my stall i went 12.88@108 on radials in 60 degree weather with a 2.0 60ft. In humid 85 degree weather I ran 12.81@105 with a 1.8 60 ft on Fuzion tires. It seems hot weather slows me 3 tenths/3 mph everytime. Wait until good weather and then worry if you arent faster.

I had almost the exact same thing happen to me. I ran 13.4 @ 105 on a 2.1 60' before my converter (prior to headers also). Then after the TCI 3500 went in I ran 13.3 @ 101 on a 1.8 60'. I talked to Kevin @ TCI who assured me that my trap should have gone up by 1 mph and NOT down by 4.
Turned out my AF ratio was way off (lean) and I was pulling timing. Dyno tune fixed me right up and you can see what I run now which is .9 faster and 5 mph higher with just LT headers and a much needed dyno tune to thank for it.
Long story short, I would get a dyno tune and see where you are after that. Best case scenario is you fix your problem, gain alot of lost rwhp and run great times like I did. Worst case scenerio is you gain a couple of ponies and eliminate tuning as the cause of the problem.
