Stage 2 vs Stock

This setup made – 232.0 HP / 252.1 FtLb

Peak Gains of 52 HP and 42 FtLb

This included the same fuel from our stage 1. We removed the 2nd restrictor pill and added a Grimmspeed J-pipe and Intake.

This stage made 232.0HP and 252.1FtLb TQ on our dyno. With stage 2 we found a 52HP or 29% increase in peak HP and 42FtLb TQ or 20% gain in TQ over stock. We saw gains throughout the whole powerband increasing to a maximum of 81HP at 6300rpm. You can expect 5-10hp more on 93oct.

Recommended J-Pipes

• ETS
• Grimmspeed–  NOT Available – The V2 GESi Catted J-Pipe is the only J-Pipe that wont throw a P0420
• Cobb

Recommended Intakes

• Grimmspeed– This intake functions the best from car to car. Other intakes can read differently simply by installing the air filter in a different location then the original spot.

Stage 2+ vs Stock

This setup made – 250HP / 265 FtLb

Peak Gains of 69 HP and 55 FtLb

This included the same items and fuel from our stage 2. Additionally we installed a Grimmspeed Electronic Boost Controller, Charge Pipe, and most importantly a Top Mount Intercooler.

This stage made 250 HP and 265 FtLb TQ on our dyno. With stage 2+ we found a 69 HP or 38% increase in peak HP and 55 FtLb TQ or 26% gain in TQ over stock. Upgrading the factory intercooler to the Grimmspeed intercooler is one of the best modifications you can do on these vehicles. With the factory intercooler we were seeing manifold temps peaking between 130-150 deg F by 6500 RPMS. With the Grimmspeed intercooler we commonly only see 5-10 deg increase compared to the 30-50 deg we see with the stock intercooler. This was nearly 30 HP increase from the Grimmspeed intercooler.

Recommended Intercoolers

• Grimmspeed Top Mount Intercooler or Front Mount Intercooler
• Cobb Top Mount Intercooler or Front Mount Intercooler
• • Some of the less expensive intercooler kits don’t actually function much better then the stock one so its always a good idea to do research before purchasing a intercooler. Also if a TMIC doesn’t come with or have the option to get a hood splitter its probably not that good.

Recommended EBC 

• Grimmspeed
• Cobb

Stage 2+ E60 vs Stock

This setup made – 310 HP / 305 FtLb

Peak Gains of 128 HP and 89 FtLb

This included the same items as our stage 2+. Additionally we added a Cobb flex fuel kit,  Detsch Werks Fuel Pump, and put the vehicle on 60% ethanol.

This stage made 310 HP and 305 TQ on our dyno. With stage 2+ E60 we found a 128 HP or 71% increase in peak HP and 89 FtLb or 42% gain in TQ over stock. We purposely keep the wheel torque around 300ft/lbs to help protect the weak rods in these engines. We saw gains of around 80 HP at 3500 RPMS climbing up to around 150 HP at 6400 RPMS over stock. We saw about 60 HP in peak power from stage 2+ to stage 2+ with E60 with no changes in boost.
