Hello,
I'm upgrading my 1991 Corvette to a 383SBC but the torque output is much higher than stock, especially with the stock manifold-long runners, 480Nm vs 650Nm. That would put stress on the transmission, diff and C beam, so I'm searching for ways to reduce max torque to about 500Nm. Power can still remain the same for the upper range.4500-5600. I will use stock manifold and large intake tubes AZS because I need the stock appearance so I need to do it by ECM tuning. One I know is by reducing the spark advance but this I understand would use the same amount of fuel and producing less torque/power. I thought of trying remapping the EGR to run at high throttle and mid rpm so that the amount of oxygen is reduced. Is this a bad idea?
Thank you.
