Lean Spike on bank 1 - WOT after Boost Controller install
 

Having another issue.

This time everything was running sweet until I had the Greddy Profec boost controller installed just yesterday.

First issue is, even with the boost controller switched off, I am still seeing 10.2-11.2psi boost. I don't know what my base wastegate pressure was set to, but surely it the installer did not set it this high.

Second issue, after the boost controller was installed, I am getting a lean spike on the Bank 1 AFR graph mid-way through a WOT pull. Please see image below.

Is anyone able to explain why that is occuring under WOT after the boost controller was installed? Would a bad or incorrect boost controller install cause such a blip? Everything was fine before it was installed. ;(
