Any experience with Race Chip? Specifically the GTS Black. Loving the idea of 75 hp gain and up to 20% improvement in mpg. Any input is appreciated. Adding the CTS intake and M performance exhaust very soon.

[ChristosD]

genuine do your car a favour and rather go with MHD or BM3 which are flash tunes that are far superior and safer in every way to a racechip.

[thejeremyman9]

Wow never even heard of that thing until now... but yeah, just get BM3 or MHD. The MPG claim seem suspicious also...

Also, skip the intake a get a charge pipe instead.

gaining power with less mpg

[btetier]

Dont get an intake or the race chip. both are useless. get Bootmod3 (BM3), a charge pipe from VRSF, and a bigger intercooler. those are basically necessities when you want to go faster.

Race chip is a fine tune, reliable and safe.

That being said the MPG claim is false. I have also noticed that they exaggerate their gains.

Sorry, a little off topic but generally speaking, do you get better gas mileage with a tune? I was honestly expecting a downturn in MPG, due to the added power but it actually has gone up... :

I figure it was all in my head but I gathered factual proof, so there's that..

MPG is heavily dependent on driving habits, among numerous other factors of course. But all else being equal (same car, same hardware, same tire pressure, etc), driving habits can have a huge impact on your actual MPG. I would suspect this is probably the main explanation - a lighter foot given that increased power at a given throttle %.

Everything remained the same, including my daily chores, so there is no mental bias.

I just had noticed I needed to go less frequent the pump, then I started taking notice, which then indicted that the MPG readout increased from roughly 18 average to mid-20s, after weeks of the same exact driving style, as pre-tune.

Logically, I believe your explanation is accurate because now that the power tip-in is more front-loaded, I don't have to step on the pedal as much, to achieve the same pull as before, thus, less demand/use of gas.

So weird, if I didn't notice this for myself and anyone claim an improvement in MPG, I would of strait up called BS but seeing is believing.

Yup, bolded part above is what i meant (not mental bias). For example i know when my car is cold, i feel like i am barely even touching the gas pedal. I am very conscious of letting the car warm up before i lean into it at all, and i feel like this requires more conscious effort to control pedal input after the tune than before.

The "mileage increase" is just the computer being fooled most of the time.

What’s the deal with the gas mileage claims? JB4 competitors often make false claims of “improved fuel economy” using their tuning systems. It is not possible to improve fuel economy using MAP sensor tuning and generally speaking more horsepower requires more fuel to support it. So what is the basis of these claims? It all comes down to how fuel economy is measured by the factory computer in some vehicles. Since RaceChip and other simplistic MAP clamp tuning systems apply a preset boost increase at all times regardless of gas pedal position or operational mode, some vehicles base their internal mileage reading off this full time bogus signal resulting in higher than actual mileage displayed in dash. If you measure economy using your trip meter in dash you’ll discover not that fuel economy has increased but rather that RaceChip has simply made the internal gas mileage reading inaccurate. The JB4 on the other hand generally does not negatively affect the economy readings in dash, and while it’s always true that making more power requires more fuel, with the JB4 you’re only using more fuel when racing around under heavy throttle making more power. Fuel economy during normal driving with the JB4 enabled is unchanged.

The MPG did factually improve, it's not manipulation.

Stock engines are tuned to produce a good balance between fuel economy and power for the specific vehicle model, for which the customer the company hopes to attract.

However, there also legal considerations given that regulate a vehicle's emissions standards, which intentionally prevents the vehicle from running more efficiently, without a air pollution trade off.

Aftermarket tuners don't have to follow such smog guidelines, so they can optimize the boost, timing, air to fuel ratios, ect. to emphasize a more efficient power output, over a balance (i.e legal) emission standard, from the factory mapping.

In theory that can be done with flash tuning, for example removing your cat converter can also improve mileage, but such changes are not possible with a "Race Chip".

If your driving habits are the same, MPG is the same.
If you drive faster, MPG will decrease.

Same applies whether you are stock or tuned.

Unless you drive like an old lady your gas mileage will most likely go down post tune. It,s simple math. How are you going to make more power and not consume more gas. I have bm3 stage 1 and I get about 19 mpg average.

I don't remember what i got before tune, but on my normal commute i get about 16, if i have more highway i get closer to 20. I drive like an old lady until the car is warm, but have a heavy foot once its good to go; hence, the low average. I definitely dont get higher MPG, just saying it is possible, but likely a result of driving habits and not the tune itself.

[Mike.]

go with a flash tune!

I'm at 15 right now

super happy with the racechip on mine. install was a breeze and the power increase is nice. not massive, but I wasn't looking to do a flash. def worth it!

im not sure I believe that to be true actually in terms of a piggy back unit not being able to support some fuel mileage increases. There seems to be plenty of cases out there to support this
