Keep us updated man! Ready to rip it up doing this. Just put in my new verter and I can only get 2500 on the footbrake with the timing trick. Need something new.

this is insane,
it works perfectly

i have video i am cutting but its badass

i could not foot brake more than 2900 and 2-3psi

1.81 60ft. was my best
on a unprepped cold track tonight i managed to spin all over a 1.68 60ft pedaling also

so its going to be capable of some crazy ****, it leaves so violent now.

on my first pass i have no tach and i wasnt watching hptuners. but it was absolutely retarded, i checked the log and i had it at 16lbs and 4600rpm when i left on the first pass hahaha spun to like 400ft

Thanks a lot, so you use a pin from the PCM, not at the plug on the trans?

it helps push a tight stall easier

if you have a tight converter that turns the tire before you can get more stall
then yes

it should help you

Nice run, I like the feeling when the frontend gets light like that and swings back and forth like that. 16lbs right out the gate? Once your on a well preped track and get her all dialed in your 60ft is gonna be nasty! I can see basicly this single 5$ relay mod dropping your quarter mileet by .6 easy, or even .8 Talk about bang for your buck!
Quick question, do you think on a manually controlled trans, that must be in 1st for use of 1st (but maybe all a manually setup trans needs to be in 1st is the solinoids in the proper setting?) So if you could manually switch them and also control them by shifting gear to gear you could set o be locked in 3rd when pressing the button, then onced released it would launch in 1st if its in the 1st gear position?
