I'm pretty happy......for now. I think it is time for the 2.75 pulley . I'm thinking 15-16lbs boost. What do ya'll think?

Nope, I am just too used to seeing the Radix dyno sheets and their crazy flat TQ/HP curves.. LOL I pray mine will do the same

Thanks guys. Everything done to the motor is in my sig. It is a cam/headers truck. I have cleaned up the throttle body a little bit an cut one side of the throttle shaft off. This required taking the whole electric drive assembly apart in order to pull the shaft out. I didn't actually make the throttle body bigger due to the idling issues with the electronic ones, I just smoothed out the entry a little. The 2.75 pulley is a deffinate must! I'm not going to do that until I Get HPtuners with the 2 bar map option so I can really dial it in at low boost because it will get into boost instantly with that pulley. I hope to have it in a month or so.
Our new found power was mainly from leaning it out due to it being extremely fat because I drilled out the meth nozzle from .020 - .028". It was really fat. I'm using the meth more for the octane rather than the cooling effect. I'll try and get my dyno sheet scanned and posted up soon.
500rwhp would be a nice #
I'd really like to run a 11.99 with the stock 5 speed and the stock clutch. You know since they are all so week and all.

Gunna take more than a 2.75 pulley to take out the Z

Ur going to take me for a ride right

I think the stock clutch's days are numbered since if you just barely touch the peddle it smokes it.
