From 105 kpa to 110kpa you drop the amount of fuel your adding.. Over 100kpa is boost.. You have no wideband in the log. I would guess your leaning it out to much.. Take your vacuum line off the waste gate and run spring pressure and you should be able to run 7psi.. Now this is to help figure out a few things... 1. If it is a wastegate control issue or a fuel issue. 2. You also need to correct your P121 & P106 errors to keep out of reduced power mode.. 3. Your trying to use boost enrichment and should just stick with pe enrichment as B.E. is for fail safe as well as the switch causes a lean spike. What BOV setup are you running? What plugs are you using and the gap?

Let us know if any of this helps..

Ok google had my wg and bov refranced off of infake, well dissconected wg and well went to 7 psi Should I come sraight from compressor housing. I guess wg is too big wtf had too small of one before now have too big. I guess I can change spring to heavy one but then im worried about spike.
