innovate scg1 boost spike/lean

[akdov823]

so basically i'm having a issue holding steady boost. i'm using the scg1, and seems like the boost is spiking and causing a sudden lean issue which in return leads to a sudden lean issue, and then boost cut.

for those who dont know the gauge its self cuts boost after 13afr

I am having similar issues! I can't seem to control boost. I have my safety setting to hit fuel cut at either 11.5 afr or 30psi. Well a couple of weeks ago, I went out to begin tuning for higher boost and in 3rd gear my boost spiked to 28.8 psi and I leaned out to 11.5, then boost cut. I have began to notice a flashing "o2 htr" when building boost now. Since the fuel cut moment I have not been able to keep boost down. I am leaning towards replacing the boost solenoid and 02 sensor. Have you fixed the problem yet?
