SOS. I finally got my 04 cobra back together and I am having an issue that has myself and some reputable people stumped.
Whenever I stab the throttle it jumps into boost and falls on its face almost to the point where it stalls. Sometimes even backfires. This does not occur when I slowly climb rpms. Fuel pressure looks good inside the car even climbs with rpms. I fell it goes lean when I stab it.
The car was recently remote tuned. The tuner has not been able to find an issue. I have a video but it is to large to attach, but can supply per request. As well as logs. I am in need of help as I have checked next to everything. I will offer a case of beer for whoever helps with the solution as I am now an alcoholic after this.
