Hypertech.....wow

I JUS WON A HYPERTECH PROGRAMMER OFF EBAY AND REPROGRAMMED MY 97 YUKON YESTERDAY AND I MUST SAY IF YOU DONT HAVE ONE AND WANT BETTER PERFORMANCE FIND ONE FAST...IT MAKES A WORLD OF DIFFERENCE FROM JUS A DEAD STAND STILL START OR A FLAT OUT FLOOR FROM 55 MPH..I RAN IT UNTIL THE NEEDLE STUCK AT ABOUT 105 AND SHE SEEM 2 STILL BE GAINING..hAVENT HAD THE CHANCE TO TEST GAS MILEAGE BUT IT SAYS IT WILL INCREASE..GONNA GO GET THE MAGNA-FLO EXHAUST THIS WEEKEND..STAY TUNED

Hypertechs won't give you much. About 10 horsepower. This guy does the best PCM tuning. Claims and many people back him up - 25-35 HP gain on the 5.3 and about 40HP on the 6.0.

well you dont have the 5.7 listed...

Well, my guess would be 25 + but you can speak to Lyndon at Wester's personally. It'll be better than a Hypertech. Hypertech is a toy.

I have heard that the Diablo Programmer is the best on the market because they offer more options ...

Former Hypertech owner here...

Can't speak for the 5.7s or 6.0s, but for the 5.3s, one will not squeeze much more horses. Changing and firming up the shift points will let to gain more response during shifting by eliminating the smooth lag between gears. TSL elimination is nice if you're runnin' on the track.

IMHO... Best bang for your buck (for better performance) would be a custom tune.

Sales Rep ?????

Sales Rep ?????

Ya know... Ya got ME thinkin' about that. Could it be??? ha ha ha!

Best handheld one? Perhaps. Best "programmer" at getting the most performance out of your PCM? Many folks will probably beg to differ...not unless you claim that the Diablo can do everything that a tool like LS1edit, HPTuners or similar can do--and yes, tools like those aren't for the faint of heart as far as PCM programming goes...but they offer way more customization than just about any handheld programmer--even one as good as the Diablo Predator--currently offers.

I have 2002 gmc sierra 5.3 I have the hypertech programmer I think that it is way overpriced the only satisfaction that I get is being able to go over 100 mph, and that is fine but I don't think it's worth 350.00.

What about the gains on a 5.7 any info?????

Have you made any attempts to find out this info on your own ? There is a world of info out there. There are nice gains in ANY custom PCM tune or dyno tune. Much more than a Hypercrap. I don't own a 5.7 so I really never seek info on that engine. But from surfing around I have seen threads where the 5.7 was brought to life with a tune. I gave you Wester's. Try WaitForMe tunes. PCMforLess tunes. Allan Nelson tunes. Call these pros up and ask them directly. That's the way I'd go about it.

I do smell a sals rep. I deal with drug reps all the time, and i tell them to get the HELL out of Pharmacy or i will have the VA police remove them! If iwas doing all the preformance upgrade, i would not to a re-programer, i would go with a new preformance ecu all together. Just my opinion.

By reading some posts it seems that maybe some of you believe that i am a sales rep or hopefully i'm reading it wrong. I'm jus a plain ole yukon owner that bought a hypertech on ebay and enjoyed the results and wanted 2 share it with the board..I wish i was a sales rep maybe i'd be a millionaire by now....

Lol

I'm sure no one is intentionally being offensive (at least not me). I've had the HPPIII for a few months, and the best thing that it had to offer me was the option to change the TSL & shift firmness. You'll definitely notice a difference with the shift firmness. Stock parameters have more lag b/t shifts. If you tried the programmer, you could see the difference.

I think that if any had to recommend (hands-down) which choice to make b/t handheld programmer or custom tune, they'd choose custom tune. The reason being, it's more beneficial for fine-tuning (especially if you've done engine mods).

Good luck with the handheld programmers. They're great for the mild enthusiast. For the "knee deep in performance" enthusiast, odds are, custom tuning is the top choice. We cool?!?!
