Dude, I love the vids! Wish they were longer. Way more entertaining than the Braves! That ride is stupid fast. Be safe!

thanks.. and it stayed at 550rwhp on 17lbs.. and 14lbs.. im thinking i have two culprits .the valve springs..im upgrading to duals.. and the p-trim on the turbo. 64mm turbine wheel.. but on more higher boost 19lbs you can deff feel a diffrence.. traction issus with slicks from a 65mph rolls. but im selling the turbo ,and going bigger..prob a borgwarner s475 with 83mm turbine wheelgoing for 16-18lbs...

aight its been awhile ... update.. was rollin around town 20lbs ,, lost my license for a month .. due to, to many points , had to go to court for a ticket, 30 over,, and court again driving on a susp license.. lol.. all is good now .. since then i have took the truck manifolds fliped them forward . , still runing same turbo etc.. and im trying the godspeed waste gate.. so far no problems with it at all .. retune is in the works within a week or two.. see how much more efficent flip foward manifolds are compared to the log setup i had originally..
