I rec'd a catalog from a corvette parts/restoration place. In it they offer an adjustuble Mass Air Flow sensor. It claims "insane throttle response" and "Huge hp and torque increases". It appears to have a variable resistor inline with the maf signalwire. Do you guys think this has any merit ? Initially I thought not. On further thinking, I seemto have myself convinced that a modification like this may actuall work. If so, this may be just what the old 7.4 vortec needs.
