Somethings not right with OP's car, unless its his driving. Either way, its needs to visit a dyno asap.

 

What everyone else said. Plus on Street tires you'll not likely hit low 12s with a 380WHP car. More like mid to high 12s and trapping in the 112 to 114 range.

 

108mph trap with 8-9lb's boost?

WTF?

 

yes im very unhappy with the car right now, i didnt go to the dyno tuners yet because i have an intercooler and a smaller pulley waiting to go on the car but wont be going on till the weather warms up,so hopfully when that is all done i will be happier with it for a while.I hate how if you go on vortechs site thats the hp they say your car will have and even the other guy at bbr said in the 380 range, according to the calculater im around 230-240 which sucks. I wish i knew how to do this tuning myself, i have the sctx3 but i guess you need a programmer to get into the datalogging and other stuff.

 

My buddy's 04 gt has the V2 (I think) Vortech on it, and he's been running 13.2 all day. He's on street tires, and he's sitting at 360 rwhp. It's also been ninety + at the track and high humidity, so def looking forward to the cool weather coming in. Not to mention street tires aren't helping at all when you get in those hp ranges. He's only around 6 psi, and he needs a re-tune because he just got a power pipe.

 

i used the calculators on that site before, they seem to work decent. According to it i picked up 20 hp from a off road pipe and intake

 

Yeah something is just not adding up here....I see you're in NJ? I was going to ask about DA/conditions but instead I will extend my middle finger and say I'm jealous of your racing conditions. haha
