When im in WOT, the lean protection I enabled doesn't let me boost past 5 psi because I start spiking to a very lean condition. I have my boost controller set at 10.2 psi. The car starts making like a boom boom boom noise like compressed air traveling within a pipe....

i would say you need to tighten your plug gap. sounds like your blowing your spark out buddy. take your plugs out , make sure they are gapped to .028. im guessing your plug gap is still stock , .044 or so.

I will check the gap out tomorrow. I did a few more runs today and I think it was just the lean protection kicking in at boost in WOT. Quick question, you have any ideas why I can't boost past like 6.5 psi when my wastegate spring is a 7.25psi? There are no exhaust or boost leaks. At first I thought it was my boost controller so I took it off. Still the same problem...
