Smaller S/C Pulley installed and dyno tuned
UPD picked up my car, installed all the mods and sent it to Eurocharged for the tune.
Mods are: smaller s/c pulley with the belt wrap kit, ASP idle and tensioner pulley set, upgraded heat exchanger and coolant pump, Floored Fab long tube headers, 200 cell cats, x-pipe, stock mufflers, TCU tune.
A carbon fiber front lip and rear diffuser were installed as well to clean up the looks of the car.
I don't have any crank pulleys of any kind. This is a stock crank pulley. These mods generated 518 rwhp and 555 rwtq on the Heartbreaker Dyno!!!!!

What correction factors were used?I mean I guess I could put a blow torch on the temp sensor on my dyno and say I made 520whp on a heart breaker also but i choose to put all the cards on the table and post all the weather info and correction factor used
Going by your % do you actually believe you are making 580whp 625rwt on a dynojet?

. Many 55s at the bay area dyno tune last time had more mods than yours and they did not make that high number 
Yours is super strong if the numer is right.

The car was taken to EC for the dyno tune for me by UPD because I'm in Afghanistan.




If they are slightly high, and more inline with Dynojet numbers, they are still very healthy. I would not sweat it, either way when you get back state side, take her to the track and see what she does.
Car looks great and seems to be a top. Be safe over there homey!
