are you sure that is not the vtec kicking in around 5.2k rpm ? i had a second gen b16a2 my self i ran a obd1 p28 . works fine. you shouldn't get a vtec controller with out knowing what u are doing . you may just be lowering ur hp and tq cruve making your car just slower. it sounds like you may be running rich due to wrong ecu. that integra ls shouldn't have been able to beat you. should have been slower unless he has mods . b16a2 should do about 15.5 1/4 mile bone stock
