Where were you doing runs?
I am guessing G-Tech runs? There is no way you were running 13.00 with the mods you listed (unless you have the CT20B turbo).
An expereinced driver could not hit 13.00 with your mods.
With your mods and
perfect driving you are looking at 13.3-13.5 at 16 psi of boost.
Your launch sweet point will probably be around 5500 rpms, you should shift around 6600 rpms in 1st gear and around 5500rpms in the rest of the gears. (unless you have the CT20B turbo, not the CT26).
I have no comment on your other "challenge".
As funny as this may seem, I am really not that interested in beating someone else. I go to the track for my own enjoyment and improvement.
There will be always someone faster. So what?
