Jeez you guys, actually READ the replys before you go about smack talking someone! I specifically typed out that I am a 17 year old kid who was only GUESSING at the horsepower numbers, we have NO IDEA how many we would be able to pull off!! 600 was an ESTIMATE, you know an imaginary number someone HOPES to achieve... As in, I was simply HOPING for a 600 Horsepower boost, I KNOW that isnt what I actually would be able to get without spending money. Right now, im simply looking into a 4.0 Super, and a KKM intake, and Flowmaster exhaust. Everything else are WEEKEND mods I am hoping to get something from. And before you go about actually insulting someone elses IDEAS, read into what they are trying to do, and dont be like ha ha, your screwed, your idea aint gonna go, shut up and get off of the fourm, your a dumb ***. Actually try to give idea and atlest explain why its not posible. I thought this forum was to help people with they ideas. Not to make them feel stupid.
