Stage 1 MINI Cooper S

Here are some results comparing a stock MINI Cooper S with 92 octane (purple line) to the same car with an ALTA AccessPORT Stage 1 tune (yellow line). These impressive gains are had by increasing boost and changing fueling & timing. These changes will not effect your gas mileage!

These results may vary, but this is realistically what you should find on your MINI Cooper S. Who wouldn't want 20 more HP and 40ft-lbs more torque while not effecting your gas mileage.

Stage 2 MINI Cooper S

Here are some results comparing a stock MINI Cooper S with 92 octane (purple line) to the same car with an ALTA AccessPORT Stage 2 tune (yellow line) and ALTA 3" Dual Cat Turboback Exhaust. The high flow exhaust allows the turbo to spool up quicker making more torque!

These results may vary, but this is realistically what you should find on your MINI Cooper S with an ALTA 3" Turboback exhaust installed. The additional 40 more HP and 50ft-lbs more torque is more than just noticable.

Stage 2 MINI Cooper S Vs. Stage 1

These results compare an ALTA Stage 1 MINI Cooper S with 92 octane (dark yellow line) to the same car with an ALTA AccessPORT Stage 2 tune (yellow line) and ALTA 3" Dual Cat Turboback Exhaust. This clearly shows how much quicker the turbo spools with the 3" ALTA turboback.

These results may vary, but this is realistically what you should find on your MINI Cooper S with an ALTA 3" Turboback exhaust installed.

Stage 3 MINI Cooper S

Here are some results comparing a stock MINI Cooper S with 92 octane (purple line) to the same car with an ALTA AccessPORT Stage 3 tune (green line) ALTA 3" Dual Cat Turboback Exhaust and ALTA Larger Intercooler. The biggest difference is the additional power up top and more consistent power from cooler charge temps.

These results may vary, but this is realistically what you should find on your MINI Cooper S with an ALTA 3" Turboback exhaust installed and larger intercooler. The additional 40 more HP and 65ft-lbs more torque is more than just noticable.

Stage 3 MINI Cooper S vs. Stage 2

Here are some results comparing an ALTA Stage 2 MINI Cooper S with 92 octane (yellow line) to the same car with an ALTA AccessPORT Stage 3 tune (green line) ALTA 3" Dual Cat Turboback Exhaust and ALTA Larger Intercooler. The biggest difference is the additional power up top and more consistent power from cooler charge temps.

These results may vary, but this is realistically what you should find on your MINI Cooper S with an ALTA 3" Turboback exhaust installed and larger intercooler. The additional 10 more HP and 10ft-lbs more torque at the higher RPM's is great for track use!

Stage 1 MINI Cooper JCW

Here are some results comparing a stock MINI JCW with 92 octane (purple line) to the same car with an ALTA AccessPORT Stage 1 tune (yellow line). 20 Peak Wheel Horsepower is impressive, but you will really feel the 40 Wheel HP and 50 ft-lbs of torque you gain lower in the RPM band!

These results may vary, but this is realistically what you should find on your MINI JCW. What we tune has no effect on gas mileage while cruising down the road.

Stage 2 MINI Cooper JCW

Here are some results comparing a MINI JCW with only a turbo back exhaust installed running 92 octane (green line) to the same car but with an ALTA AccessPORT Stage 2 tune (blue line). 25 Peak Wheel Horsepower is impressive, but where you really feel it is down low where you get 40 Wheel HP and 80 ft-lbs of torque!

These results may vary, but this is realistically what you should find on your MINI JCW. What we tune has no effect on gas mileage while cruising down the road.

Stage 3 MINI Cooper JCW

Here is another dyno run showing a MINI JCW with ALTA 3" Turboback exhaust ALTA Boost tube and ALTA Larger Intercooler, running 92 octane (purple line) to the same car with an ALTA AccessPORT Stage 3 tune (red line). 40 peak Wheel Horsepower increase is impressive, but where you really feel it is down low where you get 60 Wheel HP and 100 ft-lbs of torque!

These results may vary, but this is realistically what you should find on your MINI JCW with our 3" Turboback exhaust, hot side boost tube and intercooler installed.

Stage 1 MINI Cooper S Automatic

Here are some results comparing a MINI Cooper S with Automatic transmission with ALTA complete turbo back exhaust, and ALTA intercooler running 92 octane (dark blue line) to the same car with an ALTA AccessPORT Stage 3 tune (light blue line). The smooth & efficient shifting automatic tranmission really loves this new found low end power!

These results may vary, but this is realistically what you should find on your MINI Cooper S with automatic tranny. Who wouldn't want 40 more HP and 50ft-lbs more torque while not effecting your gas mileage!

Stage 3 MINI Cooper S Automatic

Here are some results comparing a stock MINI Cooper S with Automatic transmission running 92 octane (light blue line) to the same car with an ALTA AccessPORT Stage 1 tune (purple line). The smooth & efficient shifting automatic transmission really loves this new found low end power!

These results may vary, but this is realistically what you should find on your MINI Cooper S with automatic transmission. Who wouldn't want 15 more HP and 40ft-lbs more torque while not effecting your gas mileage!
