I've been doing a little research on Superchip Tuners to improve performance (fuel economy, Horsepower and Torque) and was wondering if anyone uses any of these on their towing rigs? Are they worth the purchase? What significant increase did you really see? And if your running a Triton V-10 what did you see in specific performance increase? With with I have found so far, out of all the brands, the Superchip brand has the best ratings. The Flashpaq has caught my eye the most so far.
