Red Headed Stepchild-75 Swinger LSX Swap

i have 3k stall converter in it right now, 3.55 gears, stock gearing in the th400 with a trans brake. i was running i think 87 octane on the pass and running off wastegate pressure of 14 psi. but it was coming in all at once. Ill be getting one of the motion race works co2 boost control kits as well. it should all come together nicely with a little bigger tire thanks to the minitub and a full dyno tuning session. times should be much better than they are right now. i was essentially ice skating all over the track anytime i went full throttle, and the 12.0 pass was about 1/2-3/4 throttle so that i would break it loose again

Cool, thanks for the info. Love the car. You might want to mess around in the holley EFI setup and get a 2-step rev limiter enabled with the transbrake. It sounds like the car is leaving the line on pretty much 0 PSI of boost. I would imagine you were around a 2.0-2.1 60-foot time at the track, so this is where you can make your biggest improvement(and its basically free!). I would highly recommend using a laptop(instead of the handheld touchscreen) to connect to the Holley EFI(I'm using it too). It may seem daunting at first, but there is a huge amount on knowledge available on the Holley EFI forum. There is a TON of stuff you can do with it and the more of the features you use, the better deal it is.
