after doing some mods(intercooler with piping, dump pipe, air intake, safc II, AVCR) to my car i encountered this problem.....
when the car hits approx 4500 rpms it just starts to choke, loses power...higher the boost more it chokes more power it loses....
first thoughts were that the fuel pump is not pumping enough fuel so that was changed( WALBRO 550hp )spark plugs changed as well, still problem persists........
after that coil packs were checked and tested and are all good.....
anyone experienced anything similar to this please HELP!!!!
dont know what to try next!!!
