I CAN'T SEEM TO WIN WITH MY PROJECT. IT'S BEEN TWO YEARS AND A LONG, LONG, LONG ROAD TMTL. I RECIEVED MY 6TH CHIP FROM TPIS AND THE O2 READS .04v AT WOT. I PUT THE STOCK ONE IN AND IT READS .71v. NOTE FUEL PRESSURE DOES NOT DROP. I HAVE AN 89GTA 355, ZZ9, AFR, 11-1 COMP., 52MM, T.E.S., BIG MOUTH, LARGE TUBE, AND PORTED PLENUM. AFTER THE 2nd CHIP FROM TPIS I DECIDED TO ORDER ONE FROM ED WRIGHT TO COMPARE AND IT HAD SIMILAR RESULTS. THIS IS THE REAL KICKER--THE STOCK CHIP IS FROM THE OLD "305" AND THE CAR RUNS WITH IT. TPIS IS NOW SENDING ME DIACOM TO SEE WHAT THE CAR IS DOING WITH THE STOCK CHIP AND THEIR CHIP. ANY RESON WHY I AM HAVING SUCH DIFICULTIES? ANY SUGESTIONS? DO I HAVE TO BY AN AFTERMARKET ECM?
