Methanol/water injection, also known as Chemical Intercooling, is one of the most potent upgrades available for your turbocharged motor. When combined with a custom tune we have consistently observed power and torque increases of 10-15% on most forced induction applications and similar to what is achieved on 116 octane racing fuel. The Snow Performance Stage 2 GM MAF system contains everything you need to complete the installation on your 2.8T motor utilizing the Bosch MAF sensor signal output to trigger injection start and flow. Methanol/Water injection requires a custom tune update to take best advantage of the octane boosting effects and cooler combustion temps (purchase separately).
