Loses power when in boost. Little help please.
So for the last few weeks when in boost I lose a lot of power. I've been running my setup successfully for the past year with no issues. The problem doesn't happen all the time. Sometimes the car accelerates in boost just fine.
When I'm down on power I also notice my afr stays closer to 13.5 to 15. I've looked at my data logs but nothing seems off. According to logs the injector duty cycle gets to 50%.
The lose of power usually happens between 2-6psi. When driving out of boost everything drives normally. I am curious whether the ecu switches over to closed loop when this happens.
My set up:
Sr20 turbo no intercooler 6psi
Begi log manifold and sgdp
AEM F/IC (MAF still connected)
AEM uego afr gauge and boost gauge.
RX-8 440cc injectors.
Thanks for any help.

nope no changes. Also I think I would see weird readings on throttle position in my datalog but everthing looked spot on.
Well I'll go ahead and get a new pump. I'm thinking deatschwerks DW200. Quite and gives me something to grow into and 3 year warranty.
