im doing a ls/vtec swap..i have a 91 ls block and a gsr head and im running it on an ls ecu......and an rpm swith to engage vtec.......im having a problem with the intake runners opening when i reach high rpm's. so im currently only using the longer intake runners. how doi get the butterfly valve to open the short intake runners without having a gsr ecu????
