[QUOTE="nasty6.6, post: 447973, member: 7676"] Hey everyone I bought a 2000 f350 with a 38r on it but looks like it has a stock wastegate spring and stock plastic intake horn. The truck only builds 5lbs of boost and it sounds like it has a huge boost leak. Running down the highway I can not talk on the phone and the radio has to be almost all the way up to hear it. Also while running 70 and going to pass the truck will not go even if I kick it down to 4th to pass. I took the edge off to see what difference it would make and now its a turtle. I did a pressure test on the intercooler and it holds 15 lbs for over a minute and then it slowly bleeds off but I think its going through the valves/exhaust Truck has 230k very little blow by and gets on average 14-15 mpg on the highway its just loud, not turbo whistle but turbine moan sounds like a turbine spooling. Sounds cool if you are riding around with your buddys but wont beat a prius... Any help would be appreciated. [/QUOTE]
