James brought us his 2016 Chevrolet Corvette Z06 to get the LT4 breathing better and to pick up a bit more exhaust note! Modifications performed by us below:
• Stainless Works 2.00" primary ID long-tube headers with high-flow catalytic converters
• MSD Performance 8.5mm spark plug wires
• Design Engineering, Inc. spark plug wire Protect-A-Boot sleeves
• NGK Spark Plugs LTR7IX-11 spark plugs
With the mechanical work wrapped up in the shop by Timmy, John strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. With 93 octane in the tank, Vlad increased the LT4's output to a solid 604.93whp & 640.38lbft! Pretty strong considering this is still on stock boost. A little ethanol in the tank, and 650whp is in striking distance!
