This '98 made good power and great torque with my tune (569/570) but needed a custom extreme MAF tune to get the best performance out of it. With an old Procharger kit, the original '98 PCM and original MAF it was a challenge and making power wasn't easy with 9.5:1 compression, 93 octane, LS1 intake and the long shared drive single 6 rib belt. It took some time to get it right but the results were more than worth it. Real happy with the power for this combo at only 10 psi boost and nice area under the curves for a centrifugal supercharger. No other changes between these pulls shows my eMAF tuning worth another 80 whp! No need for a troublesome PCM swap on this early LS1.

Mustangs 60th Birthday today. I will highlight these improvements and more later on this Classic 69 with a carbureted Cleveland.

On this 4 27 Day we highlight this c6 Z06 with a 427. I found plenty of issues created by other shops not doing their job and fixed them all. After that and a tune adjustment the customer was VERY happy to have an extra 114 whp and a safe car that does everything well including passing the emissions test.
