Hey, I've got a basically stock 92 r32 gts-t. Months and months ago i got a manual boost controller and turned the boost up to about 12-13psi and more recently i got a 3 inch exhaust with split dump and high flow cat.
It has always run great and loved to be thrashed. But last week on a f**king cold night, i gave it a hit (once the engine was fully warmed) and as the boost started to build, the engine choked. I lost all power and it felt like i was basically just rolling. I had to come off the accelerator to get the power back. This would happen late at nights and early in the morning when it is incredibly cold, but during the day it runs perfectly.
Me and my friend initially thought this was a matter of the stock fuel pump and injectors not being able to match the colder denser air now going into the engine. But the last few days i haven't been able to replicate the problem. It seems to be running fine even on the coldest nights.
What's going on? Why did i have this problem one week, but not the next?
