Hello Folks! First and foremost, I appreciate your time, and thank you for reading. I recently installed a TA-49 with billet inlet bell (brand new from Limit Eng.) I also installed a brand new HD Actuator from Kirban, Lorenz manual boost controller, PTE SLIC, including a Razor Alky kit (m15 single nozzle). The car is tuned via TT 5.7. The car is running great, but I am having an issue when Im on the highway and accelerating about half throttle. As she begins to build boost everything is smooth, up to about 13lbs (car is setup for 22-23) At about 13 lbs, the boost gauge goes erratic, bouncing all over the place and the car shutters. I verified that their is plenty of fueling, no knock. I do notice via powerlogger file, that is attached, that im only at 1.9 TPS volts when this happens, and its also right around where the alky sprays.
When WOT, this does not happen. I am wondering if this is "compressor/boost surge?" Things to look for?
Attached is a WOT file and the boost surge file and a screenshot of the log.
