hey guys i have a f250 with the 5 speed and 3.55 gear and stock tires.now first off when at full throttle my scanner shows my tps voltage at 3.8 volts and .5v at idle.when im actually driving the truck if i floor it i am at full throttle at 2.3 volts which feels like the pedal is halfway down.from there down to the floor i get no more power or engine noise change or anything.now keep in mind my scanner reads the pedal voltage all the way to the floor and maxes at 3.8v.its just my truck seems to flatline powerwise at 2.3v.so im wondering if this is normal,do you other manual guys have a dead pedal up top? my max boost i can reach is about 19psi,thats at about 3k+ rpms in 3rd 4th and 5th gear.my pyro temps will reach 1200.the truck has alway felt doggy to me,ive always thought there should be more there.my icp duty cycle maxes at 36% and icp maxes at 2475 give or take a few psi.i reach these numbers at approx half way pedal travel and gain nothing more from half way to the floor.my boost isnt instant,it takes plenty of time to build up.its been driving me nuts and i need some input from other ppl who drive similar trucks.my only mods now are a turbo back free flow exhaust.no chip on it anymore.im also wondering if a stock truck should smoke at all,i can lug 5th gear down and stomp it and not get any smoke whatsoever.thanks to all in advance,i plan on getting a fuel psi gauge on it asap to see if its nose diving under a load but i havent yet.>>>>>>brian
