    problem after header install

    i installed pacesetter lts and ory a month back, and for the most part everything is peachy. i had an issue with the y pipe hitting the floorboards, but i fixed that with some heater hose and a band clamp.

    however, in every gear under acelleration, when i pass ~ 4k rpms it feels like i hit a rev limiter for a split second before continuing.

    any ideas?

    I got a tune as soon as my pacesetter LT's and ORY were installed... now I just desperately need a lid and filter because my car is starved for air.

    shouldnt it be fine without a tune though? i want to figure out whats causing it first. i took it to autozone, and there are no codes other than the expected air, egr, and rear o2 codes.

    scheduled to get a tune in a few weeks, its just annoying for the time being. feels like it misfires just at 4k, it stops accelerating for a split second and i hear something to the extent of "pop pop pop" then the revs continue to climb.

    as for ses light, of course. air gone, egr gone, and no rear o2s. i had the codes pulled and only those came up, so its not really telling me anything i dont already know. no flashing ses either.

    I'd pull the plugs and wires and check em out, then reinstall.
