AVAILABLE NOW for 1993-1999, 2004-2005, and 2006-2011 Northstars!!!

Please read the following carefully. Our custom tunes will give you the best of both worlds, performance -AND- fuel economy. How does this work? By carefully remapping the ignition timing and fuel curves of the engine, we're able to increase the operating efficiency of the engine. At idle, part throttle, and cruising speeds, the car will seem no different. But it will be using less fuel. If you get on the throttle and go to pass someone, or put the "pedal to the metal" when the light turns green, our tune will give the engine more fuel in addition to advanced ignition timing.

YOU CAN HAVE THE BEST OF BOTH WORLDS

We don't have exact horsepower numbers on every Northstar that we tune, but we have spent CONSIDERABLE time behind the wheel with scanning equipment, data logging, and driving. One customer dyno-tested our tune on a 1997 Cadillac Deville. The results were staggering. +45 horsepower measured at the wheels, and +40 ft lbs of torque. Isn't that incredible? The EXACT SAME TUNE on another 1997 Cadillac Deville had improved the owner's fuel economy by 4 miles per gallon!

Why should you buy a tune?

    •  improved fuel economy
    •  way better performance
    •  reduced emissions (based on less fuel consumed)
    •  more enjoyment of your Northstar

We are the ONLY company that can offer such in-depth tuning for these engines! Other companies out there will sell you chips and aftermarket gadgets that plug in to your OBD-II port. They DON'T WORK!! What we sell, is professional tuning that uses your existing engine controls that just makes it work the way YOU want it to.


Hot Rod & Sand Rail Stand-Alone PCM tuning:

We are able to tune Northstar PCMs to work in hot-rods, sand rails, and other projects. The engine must be a 93-99 or 2006-2011 for us to do this. We can provide the PCM harness pin-outs and make it work with or without the normally installed 4T80-E transmission. It used to be that you'd have to run an aftermarket standalone ECM on these engines......not anymore. the factory EFI system is EVERY BIT as capable (possibly more-so) to run a Northstar in your hot-rod or sand rail.

For a hot-rod build; we highly recommend using a 93-99 block and crank, with 95-99 heads (date is stamped in the heads). You MUST use the intake manifold from a 1996-1999. We can go into more detail for your build.
