I suppose you wouldnt happen to have a wideband on it? right after it starts stumbling shut it off and check the plugs maybe you can narrow the possibilites down.

yes i retated the dizzy and i have 2 check vals but it sounds like my waist gate is fluttering i have anout 6 inches of downpipe iwanted to tap the boost gauge between the waistgate and the compresser housing and thats when the gauge freeked if you need anymore info let me know anything helps


i just odered a 5.8 psi spring hope it will help

Is there an audible chirpping when you shift? That flutter could be compressor surge...whitch kills turbos.

Once again, your typical noobie post is too vauge leaving us no option but to slam you. Be more specific about your setup and more descriptive about when this occurs and the circumstances surrounding the event.

And it wouldn't hurt to post **** either little ------achi.

no cherp but will a waistgate flutter if there is not a dumptube? just let me know if you need more info

oh yha **** www.89.com

Nice try on the **** but we're lazy and like pics...

A wastegate will flutter if the actuator is damaged. I'd be more inclined to look at your BOV but then again I don't really know ---- about your setup. Post more info new guy, and some decent **** pics. :P

at school but i hav a 1g dsm bov and ssautocrap waistgate and the spring was @ 10psui and then i choped it and it opens at 6 with the aircompressor but that doesnt simulate driving conditions also have a walbro 255 and a obxr fmu with 2 fishtank chech vales i teed into the line that go's between the waistgate and the compressor housing for the boost gauge i know i need to see what it says at the mani but i wanted to see what the waistgate was seeing

Wait, you put the check valves between the compressor and the wastegate?

Sentences, punctuation, pictures. You'll never solve your problem by vomiting out a bunch of jumbled words.

whatupdohc

the chech valves are between the mapsensor anr the mani. I do not have a digital camra.So pics will be hard i am sorry no **** at school but will make sure to do. When i get home

SmellySOHC
