Are you saying that you lose traction and spin your tires from 27mph? That's impressive. I can't do that from a dead stop with my setup.

He knew we were racing because I asked him to just to see where I was at. I also kind of know the guy. And this is no BS. When I'm on concrete at 27ish and kick down it burns the tires for quite a while then gets traction and then spins in second for just a little bit. Out on the highway when I kick down it spins yet too, but not as bad (Black top). All I have is the Whipple, Westers tune for the Whipple, 42lb injectors, Doug Thorley Tri-Y headers, LT-1 E-fans, T-stat, Open air K&N, Corvette servo, and free mods. Truck has 3.42 G80, 20" wheels with 245/40/20's (27.7 tall) And it is bagged too. And um I kind of ordered a smaller pulley today to put me at about 7.5-8lbs of boost.

BUT NOW I HAVE A NEW PROBLEM........
After I got the whipple on It would always put out 59lbs of fuel pressure at full throttle. After two days now when I go full throttle it will put out 59 right away and then instantly drop down to 40-45lbs. NOT GOOD. If I ease into it, it is fine untill higher rpms in the next gear, but if I just mash the throttle it will drop. Is my fuel pump just getting weak? It has a newer fuel filter on it (5,000 miles ish). I called Whipple about it, but since I had ditched their computer and had one custom burnt they said sorry we can't help you. So I need to find out what to do quick. Started doing this when I was running the SRT-10
