I wouldn't be pushing it past 25psi with the stock turbine housing unless you want to buy a turbo.
The amount of extra power you make above 25psi isn't much either because the compressor is so far out of its map, it's making a lot of hot air which makes the boost gauge read higher, but in reality doesn't push much more volume of air into your engine at all.
I've never seen specs for a SD, but I do know that a done stock OBS truck will push a max of 12-14 psi of boost. My best guess would be that a SD should be about the same or maybe a tad more since there are a few minor differances between an OBS 7.3 & a SD 7.3.
Mine isn't running at it's best potential and when i have the chip all the way up i can push almost 40psi out of my stock turbo and i'm going push it till it cann't take it anymore. Stock turbos take one hell of an *** whipping.
I must agree with Joe on this one. My little guy handled over 25#'s quite a lot , until the Map sensor kicked in, never put a boost fooler on, might have been a good thing though; because I would've blown it to smitherines the way I drive......:smoke
so is there a way to fix that engine light from comming on and slowin down my truck?? i have a 99 f350 with a 120hp chip and i made that waistgate bypass. after i either shut my truck off or driving NICELY the light shuts off and the thing takes off like a rocket! once i hit about 28 pounds my light turns on but i can still climb her up to 33 pounds with the light on.
so is their a way to fix it or bypass it or get something to even the boost and fuel out??
