hesitation in boost

when im building boost pressure i have a hesitation like its going to bog at 3 to 5 psi and afr reads 12:1 so i dont think its leaning out. when i let off the gas pedal and the blowoff opens then the hesitation is gone. only when im in postive pressure it bogs then a lil back fire. no cel, runs real strong when i dont build boost.

Is it beacause my spark is getting blown out? or im doing something wrong

ls/vtec, 780’s, turbosmart wastegate 7psi spring, 255 walboro, stock fuel pressure regulator, uberdata if that helps.

car idles at afr 14:3, 22inHG, 1250 rpm. oil pressure 50psi

Hope u guys can show me the way

THANKS

have you replace the plugs with colder ones. like zex???

dude same shit happens to me i though it was my turbo since i know a seal is bad…it only happens sometime mainly 2 gear and up above 4k it sounds like popcorn so to speak it as long @ it’s not wot i’m cool…

So did u ask the FSM guys about ur problem and did they fix it?

Yup sounds like popcorn poping at 5000rpm

naw they don’t know what it is either …i’ve kind of left it alone for now…i believe it’s a guage issue…as for the poppin i figured i need a real tune since i haven’t had one
