strange compressor surge but i already have the WW installed???

when i'm pulling a hill in 6th gear and i'm WOT my tuck builds up to 22 pounds of boost and then it starts surging like it used to before the wicked wheel was installed. it was fine until i put a S&B intake kit on it. also i'm gettin the p0238 code. could it just be defueling? also my wastegate is disconnected amd i used to push more boost than that, any ideas/suggestions?

when you disconnected your wastegate did you put it on a bolt or block the hose off? I will leak boost from there if you don't. Also might want to build a boost leak detector, whats your egts look like?.

WG can still open, just not as easily.
And also a WW won't 'cure' surge, just possibly fix it. If not, then a ported housing is the only other bet.

Yeah but at 400+ dollars for a ported housing your money would be better spent on a 38r or something similar, especially if you plan on keeping the truck

the wastegate line is totally diconnected. the nipple off the wastegate head is capped off with a vaccum cap and the presure side of the line at the base off the intake elbow is where i ran my boost gauge to. my EGT's never climb over 1100 degrees. they rarely actually go over 1000 degrees. I've touched 1200 degrees pullin a trailer but that was my highest spike. i've checked all of my boots and clamps and there are no signs of leaks. at 90 the truck seems to level off like it won't go anymore but i know there's more power there because i used to have no problem hittin the 100 mph mark???

egt's sound good, jesilvas said it before though, WW's don't always cure it, turbo could also be on its way out. How many miles are on it?

well i know it's a definite possibility but it's just sad to think about haha the truck has 212K on it and i don't know how well maintained it was before i got it but i've been real good to it since i bought her, minus the few nights i just wanted to go fast. I just don't wanna spend all that cash to find out it's somethin stupid like a MAP or my ICP or somethin stupid like that ya know?

i'm not getting any unusual smoke or increased lag tho, it just cuts out when i'm makin the long hard pull of an onramp and it just starts with a tss-tss-tss-tss noise as soon as it hits 22 pounds of boost, but if i lay into it in 5th gear the turbo will sing right up to 24+ pounds with ease???

Yeah I know what you mean, I hate to just throw parts at something hoping it will fix it
