Eliminate all the inherent driveability, acceleration, power and trans operation shortcomings associated with Piggyback Systems. The mechanical parts of the supercharger kit remain as is. And you don't need yet another Piggyback Programmer to self tune your trans - a major undertaking, if done correctly.     Breathe new life into your old technology Lysholm kit with the Kenne Bell Flash Calibration of your ECM and 8 new oversize GM injectors...just like the factory does. Except for moving the IAT sensor (standard practice in supercharging) there are no wires, harnesses, connections or piggybacks. And the poor fuel distribution from only 2 injectors is eliminated.  
We are well aware that the simple addition of the Kenne Bell Flash Calibration (OPTIMIZER ll™) will make our competition, the Lysholm supercharger kit, perform far better. It should. The calibrations are identical to those used in the preferred and popular Kenne Bell supercharger kits for the GM 8.1, 6.0, 5.3, 4.8. However, we have received enough email and calls from Lysholm kit owners and installers requesting the Kenne Bell Flash Calibration and injectors, that we have decided to offer them as an upgrade. Please note that the Lysholm supercharger itself is O.K. It is the "Piggyback Control System" that severely limits the potential performance of the kit. There is simply no way that tapping into some of the sensor wires and altering their true signals via another piggyback can possibly match the flexibility and performance of re-calibrating the stock GM ECM. Now you can replace that power robbing Piggyback Computer System and Piggyback Trans Computer and FEEL THE DIFFERENCE - A BIG DIFFERENCE with the popular tried and proven Kenne Bell Flash Calibration (OPTIMIZER ll™ program flashed in your vehicles ECM) and 8 new oversize GM direct port Marine injectors - just like GM would do it. Have you ever seen any GM vehicles with a Piggyback? Of course not. See "GM Flash Calibration vs. Piggyback" dyno comparison. And if you don't feel a BIG difference in driveability, HP, torque and transmission operation, return the parts within 30 days for a full refund.

Note: The OPTIMIZER ll™ is an extensive and encrypted Kenne Bell re-calibration of the stock engine and trans tables that cannot be done with Piggybacks.
*See dyno test comparison on customers GM Suburban with standard Kenne Bell/Autorotor and Lysholm supercharger kits. Kenne Bell OPTIMIZER ll™ not available for Eaton or centrifugal supercharger kits.
           
 

• Replaces all that complex wiring, potentially faulty connections, harnesses, 2 auxiliary injectors, "Piggyback Computer" and "optional" expensive Trans Programmer.
• More HP, torque and acceleration from idle to max engine speed. Torque management re-calibrated (see "GM Flash Calibration vs. Piggyback" dyno tests).
• More HP and torque at 1-2, 2-3, and 3-4 shifts (see "GM Flash Calibration vs. Piggyback" dyno tests).
• Eliminates "flat spots", "surging" and "power dips" (see "GM Flash Calibration vs. Piggyback" dyno tests).
• Firmer, crisper shifts in all gears (see "GM Flash Calibration vs. Piggyback" dyno tests).
• Feels better, even when not in boost.
• Shift points and rpm limiter re-calibrated. Eliminates overboost engine knock and spark retard (loss of power).
• Better controls engine knock (re-programmed knock tables).
• Eliminates poor fuel distribution from 2 auxiliary injectors in a dry intake manifold (see "GM "Dry" (Direct Port) vs. "Wet" (Manifold) Injection."
• Eliminates another potential and expensive Piggyback Trans Re-programmer (approx. $500) which is in no way capable of re-programming all the necessary trans functions.
• All gauges are functional 100% of the time. No fooling sensors as with Piggybacks.
• Proven and tested on all Kenne Bell Kits. 3 years experience. Just as GM engineers would do it.
• Quick turnaround. You can be up and running in 2-3 days. Send in ECM to us and we return overnight next working day with 8 new port injectors.
• We can also adjust the ECM for tire size and gears (no charge).
• Industry's best Tech Department. You won't feel isolated or helpless with our system.
• Same basic program used on Kenne Bell GM Supercharger Kits (8.1, 6.0, 5.3, 4.8).
