here's my issue, I ran wot through 2nd, 3rd and part of 4th had usual 10 psi through transition, drop to 8 spike to 11 then back to ten for a split second then dropped to 7-7.5 and stayed there consistently through those gears on multiple pulls. If it was a leak it would be present though both phases of boost. So I'm kinda stumped any ideas or help would be great.

are your wot runs after the incident do the same. maybe your wastegate vac hose popped off while driving...

they're all the same, it gives full boost through primary starts with full in secondary and drops down.

its something in the rats nest most likely. either a vacuum hose, a check valve, or a solenoid. Learn as much as you can about the sequential system and replace all the hoses with silicone ones, or you will be frustrated with problems like this all the time.

^ +1 ^ the sequential system is a complicated piece of crap especially with stange problems like that. could be a number of things. i never bothered to learn the system, i just went single. i'm gonna say u have a vac. leak somewhere. best to replace all of the hoses. remember to do one at a time or u will end up in a nightmare like i did once LoL

so...if i'm understanding this correctly. your pattern is 10-8-11 then it drops off to about 8spi again. very possible its a soleniod or a vac hose but it sounds like a prespool problem to me.

polyfc

it very well could be a prespool issue, i replaced all my vac hoses 3k ago and checked all the solenoids at the same time so i doubt it's either of those

did you remember to put the pills back in the prespool and wastegate lines. if you did put them back in...are they in exactly the same way they came out?
