Why the attack? Wouldn't YOU like to see some dyno results or are you happy with just believing?

Here's my history on this "seat of the pants" krap: I had a turbo 400 built for a '67 Commando (yeah, I've been wheelin' a long long time) The guy swore it would pick up the performance of the rig (think this is the first time I've heard these kind of things before?) The tranny shifted at a higher rpm and shifted HARD. One would think that it was a rocket ship when in all actuality, it was simply a hard shifting unpleasant krappy rebuild that did nothing for the actual performance.

Back to the intake debate, the makers all swear about their performance gains, but I've SEEN dyno tests on a few different vehicles that show they do absolutely nothing to improve output other than make the vehicle noisier which I think has a LOT to do with how people perceive that their vehicle is faster.

So, I'm not krappin' on anyone here, I'd just like to see some dyno results.

A smooth shifting vehicle is what most people want. The tow/haul mode is on other GM products to make the transmission shift at higher rpms and hold lockup longer. The reason they simply don't make it do it all the time is because the vehicle drives harsher, and wastes fuel when driven normally. Harsher shifts are not desired for icy driving, muddy driving, or even for creature comfort.

Show me the dyno charts, I'll believe.

I'm kinda betting on another thing here too and ask any diesel guy anywhere how the dealer feels about aftermarket programing and how they affect warranty. Now, this dealer they have does it, I'd like to see how other dealers feel about it. In fact, I will call my local service manager about it and would invite others to do so before they change their program. Again, on this too, if it turns out fine, I don't see any harm in it.

I'm raising questions on this NOT because I don't want to think it works but because I'd like to be darned sure it's ok before I spend the money, the time, the effort and to ensure that I'm not a skrewed pooch with the warranty if I do.

I KNOW programmers work on diesels, but the dyno results and reasons why are clearly evident. What in this program change makes the I-5 put more power out? (besides the timing change for the 93 octane fuel) I looked at their website, and the dyno result is very impressive, IF, and that's an important IF you don't have to run premium fuel to get those results.

This service looks promising. If it's all it says it is and my questions are answered (and why wouldn't they be?) I'll be paying for it.

Huck, chill out dude, no one is attacking you. You're obviously an experienced wheeler, and you obviously had a bad experience once, but you need to get off your dyno horse man.

First off, 4 wheel dyno's aren't exactly common. 2nd off, we're not adding blowers here and expecting 100+ HP, we're talking about a basic "clean-up" tune. I would imagine disconnecting part of the drivetrain just to see a few HP on a dyno would be ludacris and probably cost more than the actual mods.

The gains are minimal, but very effective, that's the point here. You can take mine and every other person's word about their results, but I'm not going to knock myself out just to make you and all the California boys happy with our results.

I also drive a nearly 700 HP Vette, I think I can decipher from a few SOTP ponies in a slow-azz H3.
