I have a d16y8 turbo garrett gt32 50a/r 48 exh, freshly built 75.5mm vitara fjt block, the head has supertech valves and valve train, skunk 2 stage 1 camshaft and a stock cam gear .

I got my car tuned yesterday and the tuner said he cant tune it higher then 10 pounds because my vtec wasn't working. On the dyno graph it showed it pulling till 6000rpm ish and then it plat owed until red line .

I did some testes and the vtec is engaging .

Im really frustrated and i dont know where to turn .

Im just wondering if it could be the camshaft im running or something else, any information is greatly appreciated .
