Stereo & Electronics - didnt expect these numbers w/ gtech

ok.. i gteched my 01 z28 in the summer and got 4.8sec 0-60 and 13.2 in the quarter with no traction, 100% humidity and 95* weather...

so since then ive done a few mods.. "race" pasesetter LT's, TSP ORY, msd 8.5mm wires, ngk tr55 plugs, ultra z hood, way better tires, and most importantly an awesome dyno/street tune from florida's best jeremy formato

so tonight i gteched it once again.. humidity??? and a beautiful 50* outside at run time... first run, on interstate was 5.7 0-60 and a 13.7 quarter mile (i had zero traction i mean none on the interstate and shut down early since the crappy trac.) keep in mind i was cutting 4.8 and 13.2's before mods listed above and in the worst possible weather besides rain...thats alomst a full sec. slower in the 0-60 and a half of a second in the quarter (so i know its running stronger uptop if it could take back .5 after the 0-60 and shutting down early)

so i go to another road (empty of course) and make another run.. this time i was much more pleased with the results... perfect launch, no spin at all.. then i pull over to check the results and i was in disbeliefe... my new times were 0-60 4.27 and 12.27 in the quarter :eek2:

now i have a few questions

is it even possible for a full bolt on to even run low 12's?
did i actually drop a full second from above mods w/ good trac. awesome weather and the tune?

man i need to go to the track and find out for real...

anybody??

You should ask in the LS1 section really, but yes I fully believe you can run low 12s. However I'd say you'll run mid 12s, to factor in GTech error. Whats your power? You never listed it. I'd like to know what GTech says for your power too, compared to your dyno sheet.

well on a dyno i pulled 340 to the rear wheels, and that was on a crappy hot humid day.. only 2 weeks ago.. weather here in FL drastically changes literally overnight..

the gtech said 290 (i think... i dont have it in front of me)

340 and running a 12.27? No. I'd say about 12.4-12.6. And you MUST have traction to get decint times.
