Performance Tune installed.....

I shipped my car to them on a flatbed.

I don’t have dyno numbers, sorry.

The tune is actually four different tunes with a hand held controller that plugs into the OBD port. I have:

93 octane performance

91 octane performance

87 octane

Fuel Economy

Those are my four choices.

I use the car as a cross-country vacation car. I drive to Colorado a lot and can only get 91 octane there.

Also, around my home area, 87 octane is all you can get in some places.

I figured this has me covered for how I use the car.

The goal was to get the air/fuel ratios right with my deleted secondary cats.

The “aggressive” tunes maximize power for that given octane fuel. It works.

The midrange bump is impressive.

Cheers.

10/10th you can get 100 octane 1/4 mile south off kipling on Alameda Mobile gas station in Lakewood, Colorado.

4 gallons of 100 octane and the rest in 91 will get you to 93 octane

91 X 14 (Ga) = 1274
100X4 (Ga) = 400 1274 X 400 = 93 Oct

Try this formula. I believe it was posted by H2OSkier a month or so ago.
1. (Octane of fuel #1) X (# of gallons of fuel #1) = X
2. (Octane of fuel #2) X (# of gallons of fuel #2) = Y
3. X + Y = Z
4. Dividing Z by the total number of gallons of both fuels gives you your total octane number.

Propane is 110 octane... hehe

I'm gonna go back to lurking now.

..She’s just a street car. We use her for fun drives and vacations. I’m sorry. I shipped the car to have maintenance done for reliability and the fuel tuning was simply to get the air/fuel ratio right. The performance aspect was simply a bonus and I requested the ability to change the tune to allow different fuel octane optimization because we travel all over the country in the car and I didn’t want a high performance only option and find myself out in Leadville with only 87 octane available and detonating a hole in a piston.

I’m just a working stiff and had already blown my budget on the maintenance items and stretched to find the coin for this tuning. I couldn’t afford to get fancy and have dyno plots printed of HP & Torque curves. As I said, the mission was to get the air/fuel ratio correct with my deleted secondary cats and aftermarket muffler.

I just thought I’d post my surprise and delight at the added power. I was not expecting this big of a butt dyno power boost. The driveability is night and day better and the car is faster and easier to drive faster. They should come like this from the factory. I had no idea the EPA regs forced such a docile factory tune that an aftermarket tune optimized for the proper air/fuel ratio and ignition timing to take full advantage of 93 octane gas could wake up this car to this degree. It’s amazing.

Cheers!

Butt dyno's ususally mean 10-20% increase in power.

Amazing is all that counts. I typically don't dyno things unless goaded to by people I know.
