Performance Chips?

[USMC_TOP]

I have an 06 H3 L5 engine. I see the prices of performance chips are anywhere between $69.00 and a $669.00. They all seem to claim the same horsepower gains and mph gains. Do any of you know of one that works best in a 06 H3?

In general, I've always been very skeptical of chips that claim to increase HP and torque in a normally aspirated engine. I believe it is entirely possible to change various timing variables to give the engine a slightly different "personality" and maybe change / move the transmissions shift points and firmness but other than that, i'd be very leery.

Pcm tune from pcmofnc.com is way to go.

PCM tune like what telemike said is the only way i'd go.

So you guys are running a PCM? Are you getting more HP and MPG too? Or just one or the other ?

 

[3Hummers]

Haven't heard any complaints about PCM.

I've heard the PCM is awesome and have always want to do it.

We offer PCM tuning at a reasonable price, $199. I might be a bit biased but I think it's one of the best bang for the buck modifications that you can do! On the I5's we usually pick up 10-14hp and 1-2mpg, along with much better responsiveness. For the automatics we change the shift points, firmness, and also torque management for better placed shifts with a more sporty feel. We can also recalibrate your speedometer (lots of you run larger tires) and account for any modifications you might have. We also have a great electric fan kit for these that's another easy 15hp!

Nah, it's not too good to be true. We're not making ridiculous claims like some - there is no way anyone is picking up 40hp for instance with just a tune. The 10-14hp that we are able to pick up is a much more realistic goal. It's not just the extra hp though, it really changes how the truck feels and responds as a whole!

Both! Better MPG and more HP go hand in hand as we're helping it to run more efficiently.

My pcm should be back in a few days from pcmofnc. For me, there was no question. The benefits of the their tune covers all bases I feel needed addressed. As Kelly said, it's a whole package.

I think I'm the only one that didn't have a good out come with pcm. Before I installed the tune I was getting 15 mpg and then after the tune plus the e-fan I was hoping to see 17 mpg but that didn't happen. Now I get 13 mpg and looking to get a custom tune made for me, I take it way easy on the pedal and going up hills she feeling like she really trying to hard when it doesn't need to be.

I would say negative ghostwriter but with the "stage 2" chip from JETS I "think" it worked because that was what I traded out for the tune. Also when I had the chip I also had a JETS mass airflow sensor that would trick the engine to dump more fuel and even then I was getting 15 mpg. Like I said I've been running 13 mpg with a OEM MAF sensor and not happy at all.

Isn't there something you can do where you plug something in, go drive around for 20 min or so and save the data collected to send it in to better customize a tune?

Sure is but I'm just going to have a guy in the passenger seat and hook up to the OBD2 and then get a custom tune to help me out.

Nice!!!

I thought I'd revive this thread and ask about long term effect on engine reliability etc after chipping. I'm shopping for an H3T, but want only a V8 because I could get out and run faster up the hill to our house than my 3.5L. Most chip posts I saw were instant "wow" reports; but what about 50K miles later? It would be easier to find a H3T 3.7L and chip it than a find a 5.3; and on paper there isn't a huge difference. So if any long time H3 owners have put a lot of miles on chipped engines, 3.7 or 5.3, I'm all ears...er...eyes.

The most noticeable difference comes from the changes to shift points. A trans that shifts fast and firm will last longer than a mushy one. The only thing that could cause issues is if the program makes the motor run lean or rich. Shouldn't be an issue with a conservative tune.
