[QUOTE="n0th1n, post: 1063478479, member: 9249"] wow, many opinion. try use no filter, and check your exhaust gas with wideband sensor. then compare the result with wideband when using original filter. will it be same? (normal ecu will maintain stoich) some more, higher air flow, such as velocity stack, you will feel the engine sluggish at low/high rpm (depends on the length of the V.S) why this happens? ecu cant compensate the higher volume of air. to overcome, re-tune air/fuel ratio and ignition.
