- Soler Throttle Controller makes a HUGE difference in feel, totally reversible and warranty safe. These cars have a throttle map that is equivalent to an SUV from the factory for the first portion of pedal travel, per Soler calculations, hence the initial lag on both A10s and M6's.

- Weapon X Motorsports Billet Lid does add some nice responsiveness down low from airflow gains. Noticeable SOTP gain from my buddy's personal experience. Totally stock tune safe.

- Remove the snow ingestion cover from the OEM intake area in the bumper. The car wont make more power but it will build boost even faster adding more responsiveness to it. Verified on my buddy's car.

- Change to lightweight 19" wheels on 285/30 and 305/30 profile tires. This will reduce overall tire height and amplify torque output in a very noticeable way. Your trans will shift fine still but your speedo will be off. Verified on my buddy's car. APEX ARC-8 19's work wonderfully and are cost effective.

- Stickier tires (R888R) in the rear for max grip to make the power already there more usable. Note, these have low treadwear for sure and are noisy tires comparatively speaking, but they work wonderfully.



The above mods (only one of which is pricey) will make a very nice change in feeling of power and responsiveness with a bone stock tune. You can always run some 100 octane race gas VP100 or similar for up to 30 more hp on stock tune, as shown on Jannetty's dyno, but that is expensive. My buddy ran a 10.91 @ 128.4mph with the above mods in 70 degree temps in Georgia at Atlanta Dragway (now closed), bone stock tune, 93 octane gas, stock exhaust except an axleback, stock intake, stock TB and the R888R's aired down to 24psi. Most of the gain is from the wheel/tire downsizing gearing effect and the grip but the rest didnt hurt. He intended to take it back with a tank of VP100 but the track is closed down now unfortunately so never got to test it. I was there for the runs, there were many in the 11.1X's and 11.0X's and he cracked the 10 on the 2nd to last pass in the evening when it cooled a bit.

There are no power gains from a blower lid. Its purely cosmetic and adds a little more blower whine.
