My truck has the 4.8L engine so after I put 33" tires on it I thought the only way to get my power back was to change the gearing. I was wrong! I`ve only used the 87 octane tune and my truck already feels crisper than it did before I put on the 33's. The ability to correct and firm up my shifts in addition to the extra power is well worth the money. If you are even considering buying one just do it. You will not regret it!
