POWER YOU PAID FOR BUT SELDOM USE:
We understand your Duramax has plenty of horsepower... but we also know that you seldom use this PEAK power.
WHAT IS DE-TUNED "STOLEN" POWER AND HOW DO YOU RESTORE IT:
In 2004 diesel engine manufacturers were forced to add emissions equipment under Tier 2 Standards and DE-TUNE the engines under 2200 RPM to pass emissions testing.
The FACT is DE-TUNING is "stolen" power which is the main cause of poor fuel economy and sluggish throttle-response (not the added emissions equipment as many believe)
While this DE-TUNING practice satisfies emission standards... unfortunately it also costs you low-end performance and fuel mileage...Bigtime!
On one hand you paid Big-Money for peak power you seldom use... and on the other hand you paid Big-Money for low-end performance that has been stolen to meet mandatory emissions standards.
