So i have a 1985 buick grand national. And my issue is that when im driving it never goes past 0 pounds of boost but i can hear the turbo spool up. I was thinking of opening the wastegate more but then again i dont want to overboost the motor.

Yeah understood, ok I’ll try to get one. Once I do get a Scanmaster I’ll let you guys know about the data thank!!

Dude what’s your problem😂 I just came on here for help cause I’m very lost with this issue. Anyway I wanted to fix this issue cause on the highway cars at like 3200rpm, but the issue is with the a/c turned on at 3,000 rpm it stutters constantly. But when the a/c is turned off it runs fine. Any...

So it’s a very weird issue now it’s running great no issues. Spark plugs I have them gapped at .32. I also just installed a boost gauge to see at what boost it stutters at but so far it’s running great so I’ll let you know what happens

Update: car will run good with a/c off but when I turn a/c on it wont go past 3000, when it hits 3000rpm it pops really loud

I unfortunately dont have a scan master, but once I get payed I will defiantly try to invest in one

But what I find odd is it doesn’t do it all the time. It will run good with very little stumble, then I let it sit turn it back on and it stumbles back to where it’s undrivable. I’ll definitely consider it maybe might have to re torque the heads down

Ok I’ll do that. Unfortunately I do not have a Scanmaster which does make diagnosing a lot more difficult.

I have a 1985 buick grand national has upgraded 65mm turbo I think, 42lb injectors. Upgraded walbro fuel pump turbo tweak chip. And has a 86-87 ecu. The issue I am having is when I first turn it on and drive it around runs great just has a little stutter under super heavy boost. Then I park it...
