This customer drove his 2016 ATS-V M6 in from eastern New York to have our Purple Belt Performance Package and Mace Stage 1 camshafts installed.  We did an E0 to E75 flex fuel tune and the car laid down 610 whp and 612 wtq on E47.

This customer shipped his 2016 ATS-V A8 all the way from Washington state to have our Purple Belt Performance Package and Mace Stage 1 camshafts installed.  We did a full E0 to E75 flex fuel tune and the car put down a very impressive 639 whp and 677 wtq on E59.

This customer has our Purple Belt Performance Package installed.  Ethanol content was kept to E44, since he has the fuel cam, but not HPFP internals.  Car produced a beautiful powerband with 578 whp and 557 wtq.  Once he adds the HPFP internals we plan to get back on the dyno, add some boost and cross the 600 whp threshold.

This customer drove in from Indiana for our Blue Belt Performance Package.  We installed K & N air filters, Brisk spark plugs, Tapout intercooler fill/bleed kit and catless downpipes.  Car made 516 whp and 518 wtq on 93 octane pump gas.

This customer drove in from Georgia for our Purple Belt Performance Package, along with the new Caddy Issues turbochargers and Tapout Stage 2 cams.  Using the industry standard SAE correction factor he put down 744 whp and 816 wtq on E87 fuel.  This is the most torque ever produced by an LF4 engine.  And the area under the curve is monstrous.  Notice how the torque and/or horsepower was above 700 all the way from 4,000 to 6,800 rpm!  Switching to STD correction factor boosted the numbers to 761 whp and 835 wtq.  Engine block, rotating assembly and cylinder heads are all still stock.
