Anyone use the "Flashpaq" tuner to get more power out of their 6.0 GM, and does it work? I called them and they claim you will get 30 more HP using their tuner in tow mode. I was just wondering if anyone else has used one and if it helps at all... Thanks

I never understand why people insist on modifying their factory tunes. OEM's spend millions upon millions of dollars testing their calibration programs to ensure they are safe and will work in all environmental conditions.


seriously, what are you going to do with 30 more hp that's only available at Wide Open Throttle? Even tho it's claimed they get that much, at what fuel economy cost?

I have one (Predator Tuner) on my Dodge Charger, because that car is modified. There's one on my wife's Dodge Challenger, 1st because she won it as a raffle prize at a car show, and 2nd, because I HATE 1-4 skip shift.

On my F150, used for towing, not a chance in H E double tooth picks.

This is why I am asking because I know nothing about it. I don’t want to be wasting money on something that doesn’t help or work. Thanks for your advice.

We live in a world made up of bell curves and this topic also lives in a bell curve

Automotive OEM's design their products to all kinds of bell curves and this topic is with the ICE bell curve

OEM's has to have enough duty cycle for performance for the worst conditions out there and still perform to specifications. Plus longevity to survive the warranty period(s), plus a bit. Not enough and their product will not live long enough and cost in the service department(s). Too much, and they have left too much on the table to lose money and/or not be price competitive

The ICE is not a stand-alone component/system. There are many other components and sub-systems involved

Tuners play with this ICE bell curve to push it from where the OEM chose (normally the mid point) and pushes it towards the high end, which has less longevity and/or duty cycle

They spend millions upon millions to ensure their factory fuel mapping meets emissions first. In many cases, the factory mapping may reduce engine life just to meet emissions.

Take my F150 Ecoboost for example. On my data logs, the factory emissions mapping would cause the engine to have a significantly greater amount of knock events versus my emissions removed tuning which allowed it to run more efficiently with increased timing.

Then there was the EPA mandated cylinder fuel cutoff if the engine has more than one misfire in a certain amount of time. The Ecoboost intercoolers were not allowed to have weep holes like many older turbo charged cars used to have since the EPA does not allow unfiltered air to escape the engine. This caused moisture to pool at the lowest point of the intercooler and would sometimes get ingested by the engine. Not enough to harm it, but enough to cause a few misfires which would then cause the truck to shut off all fuel going to those injectors for 30 seconds causing a dangerous bucking situation with low power. Why? Because un-burned fuel will damage a catalytic converter so the EPA forced automakers to have this in their programming.

Then there is the fact that the factory mapping is generic for many situations as you stated. Custom tuning allows you tune the truck specifically to how the owner uses his truck instead of the one size fits all factory tune that is safe for ways the OP is NOT using his truck.

Both my current diesel and my old Ecoboost had tunes for unloaded and loaded driving that I can switch to depending how I was using my truck at the moment. If I wasn't towing, then I would have it on a street tune that was more fun to drive with greater efficiency. When I was towing then I would flash my tow tow which reduced power output, but altered the turbo mapping to make torque come one sooner.

Also, with most modern trucks, transmission shift points and torque converter lock up strategy can be altered as well. The stock trans is often tuned to shift too soon to conserve fuel leaving you in too low of a gear and too low in the power band when towing. Not only that, but the factory converter may not lock when you need/want it to and the throttle may be programmed with a lot of lag. Custom tuning these things alone without adding any power makes a huge difference in driveability.

OP, I would not go with any "canned" tune like the Flashpaq. They are just that, a canned tuned with just a little horsepower over stock and most don't even alter shift points, torque converter lock up, and/or throttle input. I would go with a custom tune from places like 5 Star Tuning. My cousin has a tune from Black Bear Performance on his 6.0 and loves it. Either will make a custom tunes specifically for you and how you use your truck, and also do trans tuning as well.

There are a lot of hicks around here who like their diesels to blow black smoke. That's quite a thrill for them.

Is this what the early Eco intercooler problems were? Something that could be solved with a 1/16" drill bit in 5 minutes? Sounds about right. I work almost exclusively for public agencies and am astounded daily with ignorance, bureaucracy, and just plain lack of comprehension whether hereditary or programmed...lol.

The only tuner I recommend for GM is Black Bear. While I agree that you will not get much more power in the rpm range you want to drive (<3000rpm), the most benefits come from improved throttle response, transmission shifts and set points, as well as removing GM's "Torque Management".

Yeah, mine did it several times in hot humid weather within the first year I got it. Dang near scared the **** out of me the first time it happened. After doing some research on what was causing it, I drilled a 1/32 hole at the lowest point of the intercooler and it never did it again in the several years I owned the truck. It also fixed the issue for many others in the forums as well.

I was able obtain a PDF copy of Ford's response to the NHTSA investigation on the cause of the issue. I figured that was why there was never a recall on it since the cause of it was due to EPA mandated programming and not allowing a weep hole.

Since I have a GM 6.0 I recommend the black bear auto tune. Really wakes up this engine, reduces TQ management and does provide better economy if u keep your foot out of it. I like my tune, it solved a few issues for me, most noticeable was the pedal lag and lazy tranny shift. I paid 600.00 for mine. It’s simple, he sends you a handheld scanner, plug it in, drive and download. Afterwards email him the downloaded scan and he ask you what you want from you tune. He then emails you back the new tune, you then download it on to the auto cal handheld unit, plug it into the truck and download. GM 6.0 will gain 35-40 horse with 50 TQ on the performance tune and 91 octane. I use the normal tune at 87 octane. If towing I use the 89 tune. I have used the 91 tune after a few tankfuls and was able to burn the rear tires.... of course not my style but non the less it will do it. Anyway the normal 87 tune removes most TQ management and you will gain some HP and TQ. Overall I like it and have been using the tune for a few years with zero issues. Blackbear never tunes your truck to exceed where it should be, there no crazy blow you engine up within a short distance tune, Justin is the guy who owns it and really is a knowledgeable guy and keeps everything in check. So that’s my take, I zero issues with it and it has given me a noticeable performance with increased mileage and corrected a few GM quirks... let me know if you have questions.
