Back in the day when I had a mail order tune and got dyno tuned I gained ~30rwtq at 3000 rpm's from the tuner taking out timing... 
Vids of my junk going down the track...
Congrats that car is moving. Get it to 1.4 sixty and you got a ten. I would think that PT4000 would get you there. What is your best sixty on that converter ?
My car doesn't leave hard either only cuts low 1.6's I have plans for a new converter come spring.

nice runs man
I would get it on the dyno and get it tuned if you continue to race it. I'm sure you would hate to hurt the car.
I am surprised it doesn't 60ft harder with the PT4000, but it's still fly'n either way.
and as mentioned the PT4000 most likely isn't going to be too happy on the gun

My spray plans include changing out the PT4000. FTI (a new sponsor here) is making itself a big name with spray cars here locally, so I might give them a shot next time around. I've met the owner of FTI and seen the insides of their converters, they are built tough man....
I'm honestly surprised the car doesn't leave harder with the PT4000 myself. If I stall the car up it leaves even softer, so I have to keep it around 1500 RPM for my best 60' times. Not sure if the 2.2 STR being on the lower end keeps it from hitting harder or what. Best 60' is a 1.556 so far.
But yes, it will see a dyno before anymore track time.

oh yeah, btw have you done any weight reduction to your Z28?
thanks.

Verdad Gallardo ya its possible normally they are low on timing and lean? so more fuel and a lil timing will make ton better....but most cars that dont 60' with the right parts its becaust they dont have enought timing down low so it wont hit hard...seen a all motor ls1 pick up .25 in the 60' from timing alone
