twin turbo truck power drops @4500rpm
hi guys,
I had a truck the other day on dyno with twin turbo kit and cam I have tuned several similar setups with good luck making 700whp, whoever with this particular truck something is weird it feels as if it hits a wall @4500 rpm and power drops throttle doesn't close at all I tried several things advancing cam and retarding with same results.
