I've always tuned my cars, but like to wait until there is some feedback about it. I think so far there are tunes from Pogea, Alfa9/Biesse, Eurocharged, VividRacing and Enzo. Who else is providing tunes, and what tunes have people seen installed?

We will be releasing our QV tune within the week. We're very, very pleased with the final results.

To capitalize on power left on the table from the OEM/stock tune.

Manufacturers are required to build in very rich stock engine tunes to provide safe operating parameters which take into account varying operating conditions (temp, fuel quality, driving styles, etc.). AND still provide a drivetrain warranty.

Aftermarket companies can lean out ECU tunes that add power/improve power output/delivery characteristics, improve fuel economy (when not flooring it!), while still retaining safe engine operating parameters.

It's a lot of wizardry that I am perhaps barely adequately explaining, but have enjoyed for many years on my 2003 Evo and current, 2013 Evo.

Modern turbo engines from various manufacturers have enjoyed huge power increases from these ECU tunes. It's a fantastic way to increase enjoyment of your car, IMO.

Of course, this does void your engine/drivetrain warranty...as I'm sure others will quickly scold you for. But hey, it's your car. I've had ECU tunes on my GTI, and both Evos without incident. Some cars take better to tunes than others, anyone would be wise to do their research before moving forward with the decision to get one.

Does this engine really leave that much power on the table without compromising reliability and not going *boom!*? 2.9 liters producing 505 HP strikes me as probably boosted within an inch of its life already.

The QV has pretty low boost considering it's power. It has less than the Fiat 124 or Alfa 4C, and they did leave a bit on the table.

standing start improvements are more likely to come from a free flowing air cleaner - and tires.
near as I can tell, tire spin is the limiting factor already, except at really high speed, so moving the power curve, or even increasing power, might not give greater results except in the ability to smoke em.
I would guess the enjoyment factor would be the justification, except for track use where the improvements may be utilized more easily.

What seems to be left on the table as “tuning margin” is in most cases not margin. The tuners see it as such because they are never really able to monitor readings that indicate an engines mechanical limits such as piston and cylinder head temperatures, cylinder pressure, turbo speed and turbine inlet temperature. They usually plug in their tool open a couple of maps and modify them and then check on the dyno what happened. It is a very crude way that I would personally classify as development undoing rather than abuse the term development.
Of course there are sensible and empirically experienced tuners out there that could release some power that in conjunction with a sensible driver could lead to a lot of happy miles, but on a gasoline engine with 26+bar BMEP I would personally not touch it even if I have had many of my previous cars tunes in various levels.
I’m not only talking as an enthusiast but also based on my engineering background in combustion and performance engine development for some well knows engine manufacturers over the last 15 years.

I don't recall ever seeing or using the term "tuning margin". Obviously you don't want to tune your car, and that's just fine. It's not for everybody. There are people who think that the factory has everything just right and optimized, you are clearly one of those people. However some people want more power, or other changes, and for those people, we will offer a product that delivers.

Aside from the hesitation at launch, I can't imagine needing more power in this vehicle without AWD. Well, unless a tune is developed that also includes a Launch Control feature...

That's the challenge.

Everyone wants to add AWD for quick 0-60 times, but...it dilutes steering feel/response, adds weight, unbalances chassis. So AWD isn't without compromise either, which is important to acknowledge.

McLaren/Ferrari do well with RWD. ELSD helps too, which the QV has.

I do love AWD monsters like the GT-R, 911 Turbo, but...in this case, I'll stick with RWD for the QV.

Greg - I had Renntech tune my AMG. In addition to remapping the engine, they were able to turn off the engine shut-down/restart feature. Will your tune do that?

That's absolutely right!
I am mainley interested in beeing able to control the start myself and would gladley pay for a tune for just that.

Mr Donohue has something to say to you:




I think Mark Donohue's point is valid. Once the car is moving fast enough so that acceleration is no longer traction limited, more power is a good thing. In the Giulia QV on a dry surface that's around 40mph, maybe lower in conditions with really good traction. I think most of us drive our Giulias above that speed all the time, thus some of us want more power.

Launch control would not help here for two reasons. First, the car is traction limited off the line. This isn't a big turbo Honda that needs help from launch control to get the turbo spinning off the line. Second, it has a torque converter which in turn has a maximum stall speed, so if it had launch control it would have be set to such a low rpm that it would be pointless. Third, we do offer the "Full Throttle Launch" feature on our Power Pedal, so if all someone is concerned about it the response during launch, we have a much less expensive and easier to install product that deals with that.

In case you missed it in the post above, our power Pedal may be what you want. It gives the user tremendous control over the throttle, and it's a lot less money and easier to install than a tune. Of course it doesn't increase power, but it does a great job at its intended function.
