Thats what Im looking for, street real-world application. I want a little more help towing up hills, and need no more power while driving around town..Im heavy footed and all it will do is have me "contributing" to the local cities bank funds!
Lets face it, the 5.3L is a tad undersized for a truck weighing in what the AV does, and its not a overhead cam engine with 4 valves per cylinder, so there is only so much real power that can be pulled out of it while N/A.
Thats where custom tunes come in, and its more about the timing and A/F ratio than anything else with the custom tune, and then changes to the TM and shift points. After that, more power requires a Cam, pure and simple.
And Im sure I will get hell for this, but its true that CAI's dont give 10-15 more HP to the wheels, they provide better throttle response and probably 3-5 HP at WOT, exhaust same thing, 3-5 HP to the wheels at WOT. (I have both add-ons, neither turned my truck into a street dragster, and never will)
So that takes me back the Nelson I think...Ive read a lot about the handhelds, and I think im going to be happier overall with Nelson...plus if I change something, they send a revised tune for free, only pay for shipping...thats not bad in my opinion at all.

I've used handhelds in the past and been happy with them for what they were. Although generally less convenient, I prefer the services of a good custom tuner and Nelson has been consistently excellent since pretty much forever. I don't get all wrapped around the axle over competing horsepower gain claims/advertising. Custom tuning, for street in particular, is about a lot more than simply more raw power.
And before I get hollered at by the tweakers, of which I used to be one, my focus for street vehicles is to find something that works really well and then unless desires or conditions change pretty much just leave it alone. Sometimes takes a few iterations.....less if you have a good handle on what you want as a result.
