Howdy folks, problem is while the car is still building boost, while I watch my boost gauge, there is a stumble / blip right as the vacuum goes to 0 and starts turning into boost. It does this pretty consistently, feels like only one small misfire. The more throttle I'm giving it the harder the blip / stumble feels as it crosses over into boost. I never feel this blip so long as I never enter touch boost.
Aside from this, the car seems to start cold/warm, pull, and idle perfectly fine, no issues with stalling after pulls. This behavior has existed since before my engine rebuild and has persisted through new and gapped spark plugs.
I've checked and retightened things a few times now for boost or vacuum leaks but I will try to smoke the system if it's still the consensus. Fuel pressure tested good at 37psi.
Setup: I've got an '86 na2t 5spd 2+2 GLL with an eBay t3 turbo, front-mount relocated, with an '86T ECU and injectors, not running an o2. All EGR/Idle controls etc are gone. Using stock MAF, placement (picture) is 2ft after any bend. I don't think my MAF has any screen or anything on it...can anyone speak with experience about this being necessary?
I'm wondering if this is something I will have to fix in a tune being that I'm running a not-stock turbo
Thanks for any input!
