_M_ said:Like it's surging?
Pretty common issue with a lot of Strykers. A fuel controller will help, but an intake, exhaust, and tuner will get rid of it for good.
I was actually really surprised how smoothed out it got with just the intake, drilled baffles and no programmer though. Maybe try the air of mod.
Here a thread where some fixed the surging issue without a fuel controller.
I drilled 4 half inch holes in each pipe and i want to keep the the pipes and add an air kit but no fuel controller. Is that the same set up you mentioned? Will it run OK set up like that w/o a fuel processor?
