As the title says, I'm helping a buddy try and get this thing dialed in a bit before heading to the dyno. At 1/2 throttle and 3/4 throttle, all is good. However, at WOT, the MAF hz starts to go in the 13xxx where I can't add or take out fuel. At the moment, it is extremely lean. I have upped his boost-a-pump voltage as he is running more boost than we thought (looking at a gauge) but is there something else I am missing that would help solve this upper rpm fueling issue.
Thanks!
