Updated topic title as I think we could use a general thread to discuss all options without getting into too many specifics of each, so this can be it.

If specifics are needed on a certain tuner's product please open a dedicated thread about it, as I have done with for the Duramax Tuner product.

Can you link those threads in here?

Custom tuning

Has anyone looked into custom delete tuning from a company like Garmon Diesel? I live pretty close to them and it's $100 for 3 pulls and $100/hr for tuning. Wondering what that $100/hr would equate to for a good delete tune? Would it take longer than an hour to write up a delete tune?

A typical tune is 450-650 depending on geographic location and complexity of the tune. An hour would be a copy/paste hack job. The license fee to unlock your VIN isn't free.

Every canned tune started that way. Innovative tuned on my truck for several weeks, tuning and logging and tuning and logging in order to get it as perfect as you could ask for. Furtunately on a diesel canned tuning is very safe and reliable once a tuner has put in the time to get a solid tune. If that shop has done them before, they'll start with a canned tune they've proven and will just log and fine tune in your truck, I'd trust that. If they haven't developed a tune for this truck yet, I wouldn't trust an hour or two tune.
Good advice. I did my initial tune with Innovative and they did the delete last week. So far so good, amazing what a tune and exhaust will do on a diesel. So much crap on that factory exhaust. In did the AFE downpipe back.

Performance results with tunes

Anyone have pre and post tuning results in their Colorado/Canyon for 0-60 mph runs or 1/8 mile, etc. All of the tuners out there only show dyno power/torque curves, which does not say much about street performance. We are looking for real life info from tuned owners. We are so looking forward to getting our tune released. I think it will shake up this market.

You must be new to the programmer(at least diesel) market, as I've owned Duramax-equipped trucks since 2004, buying a programmer for every single one, and I've never seen a programmer manufacturer(PPE, Bully Dog, Hypertech, Banks, or Diablo ) provide 0-60 or 1/4 mile(and you're expecting 1/8mi too?) times for their product(s).
Prolly because they're made for diesel trucks, and diesel truck owners are generally more concerned with power and torque numbers than 'claimed' acceleration times.
Plus, the 'fun' derived from running a programmer is in the form of getting shoved into your seat when you stomp on the accelerator, not running around telling people that a 2wd,single-cab, long-bed version of your truck ran 2/10ths quicker 0-60 with the same programmer(according to the manufacturer)-especially when you own a crew cab 4wd, and it's got a 6" lift w/ 35" tires.

I was not asking about 'claimed' performance...I was asking about measured performance...big difference! Claimed dyno numbers are more common in the diesel aftermarket as we have seen, since most of these guys are using dynojet dynos which read about 10% higher than reality. The truck configuration is important for beginning performance data, but we are looking for A to B comparisons from folks, stock vs. tuned, so the data is valid as the truck is the same. We do our development on worst case vehicles for each application, i.e. the heaviest, 4x4 model available. FYI, the faster your 0-60, the more you are being shoved into your seat.

We have been in the after market tuning diesels only a few years, since 2009. Before that we worked as diesel calibration engineers for a few OEMs you might have heard of like Chrysler, Ford, GM, Caterpillar, Detroit Diesel, VM Motori and Mercedes. We are very astute in diesel engine hardware design and calibration. In the OEM world, we always measure 0-60 on every application...all diesel powered. Usually, we also do 40-60 mph passing along with 60-80 mph runs. The power/torque curve is fine an handy, but putting it to the ground in transient situations is a different ballgame. We also measure fuel economy, which seems to be amiss in the aftermarket, but this is where tuning can make a huge difference. Real fuel economy gains pay the customer back at the pump. Most every application we tune typically has a 40,000 mile return on investment where the tune pays for itself in less fuel burned. I think most aftermarket companies do not reveal this information because they can't deliver on it consistently.

what was the cost of initial and then for the delete tune? curios because i don't know if i want to delete right away but if its another $700 I will just wait and get one tune thats deleted.

Without knowing the quality of the driver and track conditions I have to take those numbers with a grain of salt too, just like dynos. Most drivers aren't consistent enough for back-to-back tests to be valid. That and I can pick track days with a negative DA to lose a few tenths with no changes to the vehicle. I doubt too many high quality bracket racers are taking their canyon to the track unless they do it once for ***** and giggles.
