i kno the mods are the turbo back exhaust... for the stage 2 map

i have the tb exhaust, an injen fmic, injen intake, and injen ic piping... stock BOV

anyway while i was pushing it around 5.5k rpm the car back fires and bogs on me... wats the deelo?

can it really be the bigger fmic and piping??? or is it something else like my spark plugs?

 

so nobody has a clue????

 

And/or your intake.

Could be something else, but you're definitely running stuff than the tune wasn't designed for.

 

Canned tune isn't scaled for that intake tube, plus you're processing way more charge air than tuned for. Protune time.
