im going to the track on sunday and ive never been to one and i wanted to know if i should race on 2wd or 4wd???????

With some sticky tires out back there would be no reason to use 4hi, but if your on streets 4hi it is

i have stock tires, will i lose power with 4wd?

05_GMC

From what i hear you lose some power, but with your mods i dont see you hooking up in 2wd. Youll still run good times with 4hi though. What kinda numbers you put down?

i spin alot on black tops but not as much on cement but when i launch i just press the gas i dont build up the rmps.... im like over 525hp to the crank, but ive never been to a track

Well the track is black top drug with slicks an prepped with vht or some kinda traction chemical. If your gana go 4hi drive around the wet box an when you do your launchs see what you comfortable launching at an how your truck responds to it. If your gana try 2wd gana required a big burnout an launch soft i still have had little success on street tires though

yeah i think imma try both and see what happens but i have a stall so should i build up the rmps and then launch?

In 2wd id try just flashing the converter an see what happens. 4hi start off like 2k then bring it on up. From your mods list i think with a good hard launch trucks got 12s in it. With my old setup i went 13.1@104 with 3:23s an that was cam full ex an a 75shot. Havent been to the track with the 3:73s built tranny an asp u/d pulley.
