’04 – 06 GTO
Wait there is more!…
Alternative Auto offers a wide range of performance options for these cars. Starting with simple bolt-ons like; mufflers, rear gears, under-drive pulleys, air-boxes, and custom tuning options.
And of course we offer the more extensive mods and bolt-on’s, that consist of things like headers, X-pipes, supercharger systems, nitrous systems, etc.
And even deeper and more extensive options exist with us like; cylinder head swaps & porting, camshaft upgrades, and internal motor upgrades ranging from just tougher pistons, rods, and cranks; or short block options as extensive as strokers and BigBore combinations.
One of the first things we recommend for our performance enthusiast looking to just get a little better response and feel from their modern electronic fuel injected — Ford and GM cars and trucks, is a properly done custom tune. This is a key starting point for most modern EFi cars and trucks. Our custom tunes do not always require Dyno time depending on the level of other modifications that are done to the vehicle.
Our everyday custom tunes can unlock a fair amount of performance and response from these modern EFi cars due to certain stringent guide lines that the OEM’s have to follow for the masses and other global variables. Just as a very basic example; Most of today’s cars and trucks are factory tuned to run on 87 or potentially lower rated octane fuels. Just by committing to better octane fuels, like 92 or 93 octane, we can then take advantage of this in the tuning and unlock as much as 15 to 20 more HP at the flywheel depending on the engine. Modern automatic transmission equipped EFi cars can benefit greatly from our in house custom tunes because of the extensive changes we perform to shift schedule & torque convertor lock-up.
Whether you’re looking for simple bolt ons, and tuning; Or more extensive performance work for greater power gains. Alternative Auto is now able to handle all your LSx needs. Our facility and installation experts can handle it all. From simple bolt-ons like Air-Boxes and exhaust, to deep conversions like stroker kits and full intercooled blower installs like the Magnusons and Whipples. We also offer Nitrous oxide installs too. Ranging from mild 75hp wet kits up to 200hp wet kits for street motors on 93 octane.
Alternative Auto uses HP tuner software and hardware to handle all of the custom tuning with GMs on our in-house DynoJet chassis dyno.
