Sweet!
That's why I didn't get a ticket with the car, back when it was 14b powered.
My power could be on/off under boost, and random.

I went to the track last wednesday and ran 6 times without any issue, then I went back on friday for a special race event and decided to put some 100 octane gas, before my first race the Colt was feeling fine but when I started racing just after I shifted to 2nd I noticed that it start losing some power, checked the boost gauge and my psi were barely 10 (I have my boost controller @17psi), I wasnt able to perform a boost leak test there until today and I found some leaks one on the TB and another in a coupler, I thought that was it but my Colt still doing the same no more than 8 psi now, it starts going a little bit up on high revs but not enough, any help would be appreciated! |

Check the flapper arm. When I pulled the 14b off the manifold, I noticed that the arm had shifted over. This meant that the flapper wasn't fully closing, like two misaligned circles not lining up. Also check that the arm isn't binding (remove the wastegate arm to do this). Make sure the wastegate isn't faulty causing a lack of movement with vacuum applied. I think they bleed down naturally, but it can be tested with a vacuum pump. Do you have a BCS Boost Control Solenoid installed and operational by chance? I didn't think you would. |

I guess you nailed Flying Eagle, checked the wg actuator with air and it was moving the flapper fine but also I noticed that was getting stuck for like a second then going back, I decided to take the O2 housing off and whoala! The flapper its moving sideways, right now I'm going to get the flapper arm metal bushing welded and I let you know, thanks for the help |
