Kyle you know how i feel about the Blow-thru.

your numbers are to low for something like that!

The blow thru is only for 600+hp

This is my theory, The maf is located way higher on the intercooler piping. Take into consideration your running a 3 inch.

The car isnt idleing high enough to get proper A/F mixture! because its not bringing in enough air.

By the time your maf see's air, to much fuel has been introduced!

Only thing that can solve this IMO is raising the idle to around 900rpm!
