I'm still a turbo Buick newbie, so be kind. I was at the track yesterday for the 1st time with my 86 GN which I bought in the spring of this year from a member here. I never stood on it long enough on the street to get it to build any boost pressure with the car stationary, but then again I thought maybe my converter was too tight. Anyway, I cannot get anything above 3-4 psi of boost while standing on the brake and gas while staging, period. After reading many posts on here today I feel like I may have an issue, somewhere. The car has a Precision 6131E, 60# injectors, Turbo Tweak chip, fuel pump w/hot wire, adjustable regulator, 3" down pipe. My converter is "supposed to" be around a 2600 stall, and when foot braking it I can get around 2800 out of it. Under full acceleration I get 14psi of boost as it is set now, and I have never changes the wastegate adjustment. My fuel pressure at idle is 38 lbs. All I was really looking for when I went to the track yesterday was a baseline so when/if I make any changes/mods over the winter, I will know if I did any good. At this point, with the horrible times I turned, there is a LOT of room for improvement. Anybody have any ideas on where to look for problems?? The way it was yesterday I couldn't even squeeze anything better than a mid to high 14 second pass out of it
. I was about dead even with my brother in laws bone stock 2010 Lancer. Not Good!!
