See, what most people don't realize is that Sam writes each tune specifically for the car the tune is for and he also considers the environment the car will be driven in. These aren't "canned tunes".

I'm not just saying this to sell more Turn-Key kits, I'm saying it because ultimately, it's in your best interest to protect your investment with a tune that will work extremely well out of the box.

Coming from the Subaru world, I cannot tell you how many times I've seen people drop copious amounts of money on powertrain mods only to cheap out on the most critical part: the Tune. Then they cry and complain about why their piston rings are fried and/or ringlands are broken due to all the detonation they've been unwittingly subjecting their engine to.

Another thing to keep in mind is that all of our kits use the factory MAF sensors in a blow-through configuration so that the ECU knows exactly what the temperature and density of the air entering the engine is. The beauty of that, is the fact that the factory ECU is capable of automatically self adjusting and learning based on whatever atmospheric conditions the car encounters.

For example, if you buy a car at sea level and drive it up to high altitude, do you swing by the dealership to get a retune? No. Of course not...the ECU adjusts itself accordingly. As such, the same applies to our tunes as well.

One thing I will say, is that whenever we build a car here at our shop, one of the first things we do is put one of our base maps on it to verify that it works like it should...and not once have we had to make any adjustments. Can we make a little more power than one of our base maps? Sure, but that's where the question of safety and risk come in.

See, whenever you get a custom tune, the main objective is to optimize the car for maximum power. Generally, they don't make the tune safer. They advance the timing a couple degrees and voila, you make more power. The problem is that if the custom tune is too aggressive with the ignition timing, you will be relying heavily on the knock sensor to retard the timing in the event that the engine detonates. That is a risky strategy especially considering that we are talking about a motor that was originally naturally aspirated and now has forced induction. Detonation under boost is far more devastating than detonation at atmospheric pressures.

Barring any installation issues, you will not have a safer forced induction system than our Turn-Key Kit offers. Our Turn-Key Kits make great power and work flawlessly out of the box without compromising safety.

As far as the fuel system upgrades that come with our Turn-Key Kits, yes, you can do better but at greater expense. You will not be able to do better for less, however. If you don't believe me, I invite you to price out the appropriate upgrades yourself and do the math. You really cannot beat the value, safety, or repeatability of our Turn-Key Kits.

Every other turn-key kit on the market either doesn't work, compromises safety or doesn't even come close to making the advertised power. Why spend the extra money only to have to get a custom tune to get anywhere near where you were expecting to be?

If you want a low risk, sure fire, turn-key, bolt-on forced induction kit, our GTM Turn-Key Forced Induction Systems (supercharger and twin turbo) are the only kits on the market that honestly deliver.
