Do you drive where there is a lot of traffic? Stop-and-go? Constantly hitting red lights? etc...this last tank, i grannied around the whole tank and only got 12.7ow:
I've never done a tune to any of the vehicles I've had. Are they really worth it? I've always been inclined to get one, but have no knowledge at all. I always hear the name 'Hypertech', are they any good? I just back away at the price.... usually $350-500 for the kit :jawdrop:15 all city/18.5 highway
City is usually shifting at around 3-4k rpms and highway driving is around 90 mph.
No secrets other than I use EFI Live to tune my 99 5.3L ecsb silverado
Hypershit is absolutely a waste of money. I would never buy one or any handheld programmer for that matter.I've never done a tune to any of the vehicles I've had. Are they really worth it?

I'm more into cosmetics with my Tahoe...... oustide and inside. I'd rather spend the $300+ towards Katzkins or a Corsa exhaust
Primary purpose of an intake is to remove a restriction in the intake tract... this doesn't come into effect until large airflow volumes are at play.I have the K&N 77 series intake and thought that would help, but no luck I guess.
You are gonna get crappy mileage with that type of traffic. 80% of the time you're idling - idling is 0mpg. (it actually could turn in gpm if it got bad enough)....75% of my driving is in "rush hour" traffic. I leave at 7:30am to go to school everyday, so I get stuck with the school/work traffic. It takes me 30 minutes to drive 6.5 miles. I usually drive home between 3:15-5:00pm, so I get stuck in all of the school/work traffic again. When I head to work, I leave at 4:30pm... again, stuck with people getting off of work.
School and work are less than 7 miles away, but it takes me nearly 30 minutes to get there. (Without traffic, I could easily do it in 10 minutes.)
I think this absolutely kills my mileage. I literally can't drive more than 1/4 of a mile without stopping again. I'm lucky if I hit 1 light green on my way to school or work.
