It could have been a lean condition or ignition timing fault that cause the backfire into the intake system. I would first contact the company that altered your ECU programming.

Is that the recommended octane rating for your engine?

What came out of the intercoolers? Did you buy the stock intercoolers? Was it fixed under warranty? When you say Tubi Sport Cats? Is that Tubi regular or Tubi Race? And last question. Don't Tubi make the exhaust with headers? What was the reason using the Fabspeed headers and Tubi Exhaust?

Sorry for too many questions. I am trying to learn.

Fabspeed makes a very good header for Turbo. So does Maxspeed Motorsports. Some people prefer the sound of the Tubi so they combine components. Remember when you hear the term "sport cats" it means 200 cell catalytic converters (stock cats are 800 cell and much more restrictive.) 200 cell cats are legal and will pass smog checks. When the say "race" it usually means no cats which make the car illegal on the highway (not to mention extremely loud.) Hope this helps..

As for his warranty covering the intercoolers... Probably not... If their computer detects he has altered the ECU the warranty will be void. (Unless the Porsche dealer did the mods.)

Phillip,

Thank you, that is very clear. I didn't know the difference in the past. I need to write it down to memorize. Sports Cat = 200 Cell Catalytic Converters. I am paying very high dollars to get the job done at Momentum Porsche in Houston. I don't feel like paying too much, but rather paying the right price for the top notch work. They are going to use my vehicle this Sat. to show to Porsche enthusiast. Warranty was the reason I chose the Momentum Porsche and I didn't want to get bounced around between shops if the problems arise in the future. I have a close friend and he told me that he has been dealing with Momentum for last 7 years with all type of modification work and have not had any unfair incidents from them. Again, thank you and I will let you guys know something soon about car's sound and performance.
