I suspect you could be making alot more power with 3" tubing. 2.5 is just too small. I have the same pulley combo so it should be interesting to see. Also, are you still using a 65mm TB? 70 is minimum with Forced Induction I would think.
Im hoping to see 10-12# at the plenum. are you using a powerpipe?
