5 Star tuning

I am considering having a modification done to improve my torque and performance by five star tuning out of South Carolina I drive a 2011 Jayco Greyhawk 31fs. Has anyone out there had this procedure done on their motorhomes I am interested in hearing your likes and dislikes

I got the 5 Star Tune online for my 2012 31DS and can say two things:
1- it definitely improve the transmission shifting profile - it does not up- or down-shift nearly as much on grades or acceleration and the shifts are at more reasonable points.
2- on my coach it did not change the gas mileage perceptibly one way or another, as far as torque goes it is also not noticeable to me.

Bottom line - it is a pretty expensive fix. I enjoy the shifting improvement, but probably would not buy it again (although I do not feel ripped-off). If you are mainly interested in mileage and torque I would think carefully, although I am sure it also depends on ones driving style.

Good Luck.

What engine is in the Greyhawk? Is it the V10?

I have a F250 with the 6.2 V8 in it and I have a tuner with custom 5Star tunes sitting in the center console. I haven't loaded them yet because I am still in warranty.

Subscribing to follow along.

Cheers

The Greyhawk uses the V10 engine.

Yea, I did. Love it. worth every penny! I get better low end torque, shifts better too! Doesn't sound like the motor is going to blow up going up a 4% grade.
When you do the install it ups the horsepower, torque and shifting for better driveability. Instead of me explaining everything here, check out the webpage that shows the test by Motorhome magazine:


Got a 1998-2015 V10 RV? - 5 Star Tuning

https://youtu.be/cRkBaFU2bpY

A friend went we me on a short trip and noticed that the engine was running a lot smoother then his previous trip with me. Also noticed better horsepower. Told him about 5 star tuning for his Class A. Now he has it and keeps thanking me for the heads up!

Anyway, that's my 2 cents....

Lord knows I've read just about everything I can find about the tune. I'm just a little leery about my Ford warranty should I get a check engine light and have to bring the rig in.

I just installed the 5 star tune on my 2015 Precept 35UN, Going on a 1300 mile round trip in about 4 weeks, Going to be towing, I cannot wait to give it a try, As for the Warranty, I am not concerned for two factors, 1 - The V10 is a workhorse of an engine with very little issues, 2 -Ford would have to prove that the tuning caused the warranty issue. I am willing to take that ever so slight risk to get much better shifting, horsepower, and torque. This decision is a very personal one, you have to feel comfortable with it. For me, it's an absolute. From what I gather from reading so much about it, the 5 speed, which I have, gets better results then the 6 speed tranny.
Good luck!

Just did our 2016 31 DS. We are in a CG in CA until Thursday and I am anxious to see how well it works. Was awful coming through the mountains with the constant down shifting and engine noise. Will post results on Thursday.

I just ordered mine. Chris @ 5Star tune was very patient and informative; made me feel better about it. So lets see what happens.
