New LS1 Owners - Newbie Tech - G-TECH PRO do they work well?

--------------------------------------------------------------------------------

I tryed abuddys G-TECH PRO for fun. I have no idea how clouse they are but it side that I run a 12.1 at 129mph for the 1st run and then the 2nd run was a 12.0 at 121mph. But the last time I was at the track I ran a 12.8 at 113mph that was with out the 30in injecter and a good turn, on street tries and I was shiftingt at 5500RPM and not the 6700 RPM that I shift at so who know's. I will just go to the track and see. Your info would be cool.

on street tires I believe that time would be way off unless you got a ton of work and somehow hooked up for a 12.0....

This is what is done to my RX7.It has a 95 lt1 T-56 swap,modds,CC 306,CC valve 918 spring,1.6 rocker,58MM TB,Accel 30lbs injector,accel 8mm wires,NGK plug,MSD cap & rotor,MSD coil,cold air intake,K&N filter,The PCM has been tuned by PCM for less and it has the LT-4 SCM,$10 gears, LSD.

they are usually consistant, but not accurate

I have a buddy that has the same car as me rx7 FC LT1 with a auto. He ran a 12.4 at 119MPH.On street tires.

I found it to be a decent tool to learn to drive your car, especially an M6.

Mine always seem to be accurate but the mph was always jacked up.. jusy like the 129 trap it told u ... but it was more like 5mph off for me.. Woudl say I ran a 11.7@125.. when i was running 11.8@120

theres no way you can run 12.0 in an LT1 ... j/k

I wonder if the MPH discrepancy is due to them giving you an exact MPH value, whereas the MPH you get at the dragstrip is an average over the last 60 feet. Still think they're a bit off though.
