z28 vs ws6 question
z28 vs ws6 question I raced a ws6 tonight with basically the same mods minus the lid. We raced from 40 and he pulled maybe 2-3 feet in front of me till I hit 3rd and then I just flew past. I also raced a mach with basically the same out come. From a stop I have beat the mach but have never raced the ws6.
I was just wondering if maybe a stall would help me out down low? Are there any other suggestion to help me out? Besides nitrous, h/c type stuff. I won I just want to be stronger down low.
I understand that I need a stall for launching but, right now im looking for the reason my car is so weak down low yet really strong up top..
Thanks for any help

The stock converter and PCM shift settings hold you down
in lower RPM, which hurts your launch and lower-gears
power output but they give good efficiency up higher.
Have you upped the shiftpoints to get full use of the
powerband, at least after you get up onto it in 1st?
It might be worth inspecting some hard-pull through-
the-gears logs, and see if you can notice any differences
in O2 (WBO2?) readings, spark advance, delivered torque
etc. between the 2nd gear and 3rd gear, same RPM points
(whether there is any rate-of-RPM-increase related tune
bias). 3rd gear is more steady, in 1st and 2nd the MAF is
going to be lagging real airflow to a greater degree, etc.).
Also the point where you pull ahead may have more to do
with -his- shiftpoint, than yours (like you were in low 3rd
going strong, and he had to do the 3-4 upshift, bang).

Thanks, I will try and figure out the shift point thing. most of the time i believe it was their shift to 3rd when i come back on them. but once he jumped ahead about 2 cars when i wasnt ready and i slowly creeped back until he hit 4rth and it was like he hit the breaks.
From a dig I should be ok right? Last time I raced the mach i beat him by .2 in the 8 so now i dont know whats going on. Only thing i have changed is the magnaflow for loudmouth.
