just replaced the fuel line this AM and started a new thread in the "How To Guide" section, link below. Name there is "SSROADSTER"

Took the SS for a test ride and all is well, for those who have been following, I have reinstalled the tune, and the popping and banging that I was having during part throttle is eliminated. Thinking that it was the BSR tune, when in reality it probably was the leaking fuel line causing that condition. I still may have the loss of boost condition at times, but right now it is to wet to test. There still is the possibility that the wastegate actuator solenoid is defective, as I recorded another P0234 Overboost code the other night still with the line leaking. Also it did start to leak more so even with the Liquid Metal temp fix, so the SS sat and my wife made the sacrifice of letting me use her vehicle til the part came in, what a lady she is....
But the testing after the line replacemnet today was very encouraging, quick response, no popping or banging as I stated, and no surging at all. Will test further tomorrow. All-in-all a very procductive morning....:
