leave it all alone. It's saving your stock trans from your abuse, lol. :roflmao: But seriously, examine your low pressure side first :)

Okay, just an update, I'm still getting the limp after the new fuel filter but not as often, can make it to around 100 or usually before it limps but it falls on its face around 40-60 then kinda kicks back up after 60 then falls back on its face by 80. I ordered a air dog through a local performance shop. Picking it up tomorrow, hope to get it installed this week end maybe sooner. Will report back! Thanks again for all the suggestions!

TX of course
Ask your tuners how much pulse width he has it at on the big end. He should give you a 4 digit # with us after it like 2400us.
