Todd, fully understand this is a truck and not a race car, but somehow a tune that provides less than 10HP (according to your numbers) is even worse that I thought, and surely not worth spending money on, in my opinion. Why would you flash a tune in, and "hope" you can flash it back if it has to go to the dealer, for a 10HP risk? Say you are out of town, highway bound, and need a tow to a dealer??? Not like you carry the tune and tuner, so in my opinion, why would anyone take the chance to put a tune on the truck that you have the "Potential" to have issue with? And trust me, it is NOT in the dealers court to have to PROVE the tune caused the issue, if any. Not sure, but I can assure you, all the dealer needs to see is an engine mod or tune to tottaly disqualify the warranty... look in the fine print for OEM warranties! That is a false statement, and not one anyone here should be sold on! So if you do tune a motor, you best hope you "can" reflash it back if it has to go to a dealer! I can almost with 100% tell you, the dealer will NOT honor if a tune is present!
Not sure about the rest of the guys here, but if you are going to spend any money on a mod, it has to be worth it. I am all for fun and games, but not at the risk of a motor. A tune for 8-10 HP is not worth it, and money ill spent, unless I am missing something. If you must mod, seems you are better off doing so on cosmetic mods!
Just my .02 - Rant off.
