Default Two Guys Garage - Hypertech = 120HP gain?????

You know the machanic guys on TV - Sam and Dave.

They were tuning Sam's new GM 6L deisel truck with a Hypertech handheld tuner and they claim to have improved HP by 120 and tork by 85. This was on a dyno measuring RWHP.

Is this total crap or what?

At 540 footpounds I'm going to swap my Gen 3 gas turd for a Hypertech tuned GM 6L deseil!!!!

You can get big horse power increases from turbo diesels with programmers. I sell the superchips programmer and you can get them for 100 horse bumps in the diesels, i dont know about the hypertech but they are pretty amazing when it comes to the amount of power you can get out of them with a retune.

When you can up boost by computer than you can gain big power. Diablo makes one that has 120+ boosts.

This is true. The PCM on the duramax diesels controls the wastegate. By retuning the PCM they just cranked up the boost.

Its not all boost related. Diesel engines are nothing like gas ones. The more fuel you inject into a diesel, the more power it makes. Richening up the fuel mixture adds power...and can add a lot...up to a certain point. Also just changing when the fuel is injected is worth a lot of power. Diesels have no throttle body plate. The only thing that controls engine speed is the amount of fuel being injected. I've seen stock motored Duramaxes dyno over 1200 rwtq with the stock turbocharger. The hypertech and Predator is just a fart in the wind compared to the Hot Juice box. For more info visit http://www.thedieselpage.com
