A few weeks back I had a shop install the Motiv Reflex box so that I can run port injection. Current mods done to the car is downpipe, AMS chargepipe, Ecutek tune, flex fuel, CSF intake manifold and now PI running ID 1050 injectors. When I go to do a log for my tuner (4th gear, VSC off, starting at 2500 RPM) the car pulls really nice up until about 5500 RPM then the wastegate gets thrown open and dumps all my boost and will only build 7-10 psi for the rest of the pull. I see boost get up to 23psi, sometimes 24-25psi. Tuner tells me it's boost leak, and I had the car leak tested and we fixed where it was coming from, but the car keeps doing it. We've boost tested in multiple areas of boost system, looked at the fins of the turbo for damage, and still can't find anything. All this is on fresh spark plugs, fresh oil, and an E30 blend of fuel from a good fuel station.
Has anyone else ran into issues like this? Is the wastegate going out? Just seems odd it happens right after having the PI kit done. Car seems to run fine driving around normally in comfort/sport modes.
