Now that I fixed the fuel leak I now have a new set of problems.
I installed the Hallman Manual Boost Controller and took the car for a spin. Started off at the recommended starting point of 3/4" on the screw and that was about 12lbs of boost. I adjusted it 2 more times and I was making 18lbs of boost. Then my boost gauge went to 0 and wasn't moving. I assumed the hose had come off so I pulled over and sure enough it had popped off. Not a very good coupler. I put it back on and zip tied it nice and tight this time. It's staying on and I'm still making 18lbs of boost but now the check engine light is flashing constantly. Rob's ECU tune had a knock light feature that uses the check engine light to indicate when the ECU sees engine knock. I didn't notice it until after the hose blew off the boost gauge line which is coming off the manifold teed into the line that goes to my BPV. It could have been flashing before the hose came off and I was probably just not paying attention to it because I was watching the AFR and Boost gauges.
What do I do now? Is it because I turned the boost up? I would think not because it does it on idle when there is no boost. Could it be an injector is not firing? Now I'm scared to drive it so I parked it back in my parent's garage and came home sad.
One other thing. Should I still be seeing fuel cut? At 18lbs the engine cuts out violently or whatever I set the boost controller at. In 1st gear it's a lot less than 18lbs I think. Like 10-12lbs of boost. Is that normal? I'm not able to get over 4.5-5K RPM with full throttle because I hit 18lbs about there and the engine cuts out and the car jerks pretty good. I was under the impression that it would get to 18lbs and the manual boost controller would open the wastegate stopping the turbo from making any more than 18lbs of boost but the engine would still pull and accelerate all the way to redline. Is this not how it works? Do I need to install a fuel cut defender?
Kind of sucks like this. Sure it's quick in boost but only 5K tops?? Lame. I don't think this is how it's supposed to work.
Pic of the MBC installed. I cut the excess off the zip ties after this shot.
