Is it safe to do a 80hp economy tune? is it gonna blow my head gaskets? I have heard people say things either way. i want better fuel economy and most tunes say about 3-5 mpg gain. Is that true? Any advice?? Looking for any insight either way!!! thanks
Is it safe? Maybe. Tough to say. Every truck is different. Will it blow the headgaskets? 50/50. Who knows. Drive like an idiot and the odds increase.
Don't mod for fuel economy, because chances are you'll be disappointed. Mod for power, and if you happen to gain economy just be thrilled. FWIW, the higest HP custom tunes offer the best mileage, if you can keep your foot out of it. If you can't, you risk the gaskets so...

Right, no 6pos stuff for these, plug in programmers only. I would also recommend SCT.

There are, but you don't want these. The 5R110 is physically incapable of accepting tuning on the fly, but the motor itself is. Can you see where this is heading? Lets say you're cruising down the road on a "level1" or something... you see the d-max next to you horsing around and you want to shut him up. Crank it up to "level 10", and mat it... well the power increased but the trans is still on stock settings... Not good. These trans ONLY last as long as they do and behind as much power as they do thanks to custom tuning on them. Without the tuning, the trans wont last long at all.
03/04 trucks take 5 min to reprogram
05+ are just under 2 minutes last I checked. Is that short amount of time worth damaging your trans?
Typically once someone loads an x-street tune up or something, they will hardly find any reasons to go back to a lesser tune anyways.
I DD a street tune in the winter, an x-street in the summer, then load up my tow tune anytime I hook to the camper, and load x-race when heading to a dyno or a drag strip.
