Quick advice on running 99 GT, tuner questions

[Coupe5oh]

Im going to run a 99 GT wed at the track for a harmless amount of money, i met the guy in another town south of austin at a streetrace meet, we were the first to come to a stop sign, i waited for him to stop then i rolled out and floored it, (me having a passenger about 240lbs)he didnt do anything, until i hit 2nd and let off, he decides to flybye, but he pulled me good, i couldnt catch up.

so we park and my friend tells him to open his hood, he said bone stock, and previous owner took the blower off? my friend said it looked like pullies, but i couldnt tell, so i say lets go again from a stop...he jumps in and goes for it, this time he has a passenger with a video cam, i honk 3 times and we were off, i hooked up great(love those subframes) and pulled him hard and kept a car on him all the way to 118-120 he couldnt pull.

We park ,and he says he forgot his traction control was on, but cops came and we never had another chance to run, but i chat with him online and we have a race setup at the track.

sorry so long, but i wanted to ask windsor guys only, but he said he will be on e.t. streets, and im gonna have to borrow some from my friend, any tips? i never ran stickies, should i bump timing to 16? its at 12, what rpm to launch from on 26x10.50's? im also throwing on a crank pulley 25%......thnx
