I recently did an experiment going from 93 performance tune to 93 economy. Drove a few 300 mile trips and picked up a solid 2-3 mpgs averaging about 15 mpg all around and almost 16 mpg pure highway. Any trip that length I'll likely load this tune.

The downside is around town the truck feels completely neutered. Very lazy throttle and shifting so it gets annoying. Loading performance tune again made it feel like an animal.

I'm thinking that for 3mpg, on a 30 something gallon fillup, that's 100 mile per tank difference. About 8-9 gallons of gas. That's about $30 per fillup difference.

Sigh. You gotta pay to play...

Having no experience with tunes, a good question was asked and maybe it was answered, but not to my understanding...I hear of people driving a few hundred miles when loading different tune, will the truck go from one tune to the next and be at a point for optimal usage? If I want to tow my boat on Saturday morning 50 miles to my dads, then drive 600 miles to so cal, then rip the hell out of the desert off roading, and drive back in the reverse order....is a tune for each going to work? Or will there need to be seat time to have the truck learn each tune over and over when loaded?

My tune works in all the above I don't have to change a thing unless I was to tow the crap out of it.

Just got my SCT X4 and installed the 87 perf tune since I currently have 87 octane in the truck. Holy hell does it shift perfectly now. I also don't have that annoying shudder/burp/vibration from the Corsa CAI. Now all you hear is pure American beast!!!

That's great to hear. I'd also love to hear people's opinion of the 87 performance tune vs the 93 economy tune.

I know what you're getting at, but I wouldn't put 93 octane in the mix with economy and 87 with performance. Sounds interesting though. I need to get a tune apparently. I'm missing out.

I'm thinking whether a 93 economy tune will give me similar performance of a 87 performance tune but with better fuel economy.

I'm guessing once I try the 93 performance tune I won't want any other tune, mpgs be danged. Sigh...

Do you guys actually use 93 octane gas? or just octane booster? I never see 93 octane around here...

Is there a work around to keep your factory warranty with a tune on our trucks? I know on a chevy you can have a stock ECU and swap them out if you ever need any work done. I know things are getting tougher these days but I'd hate to void a warranty on a new truck
