I just bought a used TNytro with the Alpine/Trask rear turbo. I had an exhaust leak at the flex joint coming through the bulk head.
Not sure if yours is the same setup but I have a pic I can send you if you want to compare setups. Something to check anyway.

Cracks in the bellows of the exhaust under the fuel tank is a good place to look. A common problem if running av gas and boost.

good to hear. pain in the arse. This summer I will pull mine again and come up with a flex joint that clamps in place. Make it easier to replace when needed.

Another good place that you will find boost leaks is in the gaskets labelled #4, The brass ones that Thistledoo sales wont blow apart. Ive replaced the stock ones twice.
