make sure theres no leaks post-blower? i see you have lt's but its not gonna suck 10psi out of the setup, methinks there might be a boost leak somewhere. Not a common occurance, but possible none the less.

are you logging afr's/wideband? if no, is amazon just guessing what your afr's are?

 

[tnkucan]

afr is good car idles fine and drives good

I would think if you had that big of a boost leak tuning would be close to impossible? and would run like Sh#t! You log boost through the map sensor?

 

[tnkucan]

gonna check the compresion on the motor to hopefully rule that out

did compresion test dont know how exact the guage is but they ranged from 140 to 145
