I wish that was the case. It shows .8bar on the cockpit gauge and the wastegate pipe spews flames at full boost. It looks like a bunsen burner at WOT
That should not happen. The exhaust system in that area should not be hot enough to ignite unburned fuel which means it is likely burning out of the exhaust ports. If you can take for granted that the A/F ratios are correct this condition suggests the engine is under a terrific load. If not it is mimicing that condition, possibly through timing or fueling issues.

You have done all of these radical changes and still have the same problem of low power?
Is anything getting excessively hot during operation? How about your transmission?
Way out-there question but how much does the car wiegh?
What exhaust system does it currently have? Cat?
