I get a perfect 10-8-10 pattern in every gear when ive been cruising in that gear and accelerate at wot. However when I accelerate wot through the gears i get the 10-8-10 pattern in first fine but then little to no boost in 2nd. Same pattern continues starting from any gear. Does anyone have any ideas what could be causing this? I just replaced the check valves with dale clark check valves. This did not help the problem.

 

hey i was having kinda the same problem what i suggest is checking you solinoids under the UIM. On my car it was my throttle control solinoid that was bad. Good luck
