485rwhp. I get some heatsoak issues though, so id have to run one like right as i hit the freeway. At first I thought I was losing some boost through the plumbing from the intercooler-throttlebody but its just heatsoak. I might rig up a small nitrous shot (like a 35 maybe)just to keep the temperature down.
Im not saying id punk a new m5, I'd just supprise him
