I bought it from Mike. He was referred to me by sprintex. Here's his email superchargersofokc@yahoo.com

I think it strange that I am the only person having a good experience with his sprintex.

I will say it not a perfect system. Main problems are it doesn't like to be cold. Solved that by...

Still loving the sprintex. No major problems. The only thing I don't like is changing the oil. It's very challenging to find a tube small enough to extract the old fluid.

It might be your tune. My first tune was a problematic. Surging and not what you would expect. My second tune got rid of the surge unless it's real cold. It does not like the teens. I also...

I am glad I did it. If you have 5500 to put into your jeep it's worth it. I never worry about passing or having power. I do worry about the long term effects on the jeep. When it destroys the...

Just drove from DC to Atlanta. 16.5 mpg doing between 65-70. Any faster and the mileage goes way down. No problem passing or merging.

Also, I talked to Gary at sprintex and he said there...

Glad it's working now. The next thing you realize is that your gas mileage sucks, but you don't care because of how much fun it is.

I will do it when my son gets home from school and after we upload it I will paste the link.

Idles fine. No lights on the dash. No codes in the box.

Sorry I've been out of the loop. Too many kids. I love my jeep. I have not had any problems since the original install. I had a bad Diablo tuner. Once that was corrected it was up and running...

The fact that they are in Australia is a negative. The turn times on the tunes can be a problem. My first Diablo tuner was bad. Because of the time difference it took longer than expected to...

I never have to lift the accelerator. Sometimes if I want to shift a little earlier I just tap the Shifter. For the most part it shifts where I want it too. I don't go blast all the time. When...

I am flying today and I will respond to some of these questions. I love my jeep and it drives great. Love the low end torque. Mileage is getting better. When people say lift to shift. Are...

I am not associated with sprintex at all. I am a pilot for United Airlines. Sprintex is not perfect. As for the transmission problems. I really don't have any. If I go max blast it does...

Under full throttle it has no problem shifting. It shifts around 6.2 all the way up to 80. And honestly it feels as fast as my old 77 Porsche 930.

I give it a try tomorrow and let you know.

Not to be ignorant, but what shift problems are the other units having? I thought it was a surging issue. I would expect that if I was to go full throttle the shift points would move up to around...

The fuel mileage quoted is the old fashioned way of miles driven by fuel to top off. The instrument cluster reads much less.

It seems to shift like stock now. Overall I am very happy with the...

The new tune has been installed and driven. Low end surge is all but gone. Shift points are where I like them and gas mileage is up to 15. That mileage was half of the old tune so not sure what I...

I had heard about the '12 head problems. Luckily no ticking Pre or post charging. Sprintex just sent me a tune because of the aftermarket exhaust. I will give it a run tomorrow and provide feedback...

Here are some pictures:

Pics are coming. I am waiting for a little sun and warmth. I am installing new headlights either Monday or Tuesday and I will have the front grill off. I am not doing LED lights. My TIPM didn't...

I pulled the code and 30 minutes later I got a response from Sprintex. The code is associated with the fact I am not running stock exhaust. I have a Gibson dual exit exhaust. So far, I have been...

Tomorrow, if everything works out, we are taking the jeep wheeling.

It threw a check engine code yesterday and another one last night. The first one was a misfire and I haven't checked the...
