I have been reading a lot about the XCAL2 and I think that is something I def. want to get for my truck. I also want to change my gears from 3.55 to 4.10 or 4.56 since I just got 33" tires on my truck. I have the 4.2L so I really need to gain some power back, just not sure which I should do first. Re-gear then get the tune? I did some searches but didnt have much luck. Thanks.

Basically to sum up my question, if I were to get the tune first, would it effect it any when I do eventually re-gear to 4.10?

 

If you are definitely going to get the gear changes, then you should probably do that first. On Troyers sheets that you have to fill out before he tunes your truck, it asks what modifications that you have made. So, if you are gonna do the gears anyway, I would do that first then get the XCal2. That is just my personal opinion though. It may change the tune setup if you change gears after you got an XCal, so you would probably have to send it to Mike again. Though I reserve the right to be wrong about this.

 

Cool, thanks for your input. I think I will go that route, first re gear then get that XCAL2 tune to be on the safe side.

 

yes i would regear before getting the tuning, good luck

 

Hi ChrisT,

I'm afraid I have to disagree with the responses you have been given here so far - the actual truth is, there is absolutely no reason whatsoever to wait to do our Troyer Performance custom tuning in the XCalibrator 2, and that is what will, by far, give you a much better gain in performance.

The fact that everyone seems to be forgetting is that the XCalibrator 2 allows YOU, the vehicle owner, to very simply plug in whatever gear ratio you like, all by yourself, at any time!

That way you can instantly correct your own speedometer, and thus automatically correct the shift points in an automatic transmission model (just for example) in a couple of minutes by simply pressing a few buttons on the XCalibrator 2. You can do that AT ANY TIME AFTER you get your custom tuning loaded in the XCalibrator 2 - this is a feature that it has had for quite some time, and is nothing new.

Our tuning is by far the single best performance-gaining bang for the buck, the gear change is far more expensive, especially in a 4x4, and in any case will not yield nearly as much performance gain compared to our Troyer Performance custom tuning.

Now that you know the correct facts, you may still decide to do the gears first anyway - speaking personally, I wouldn't, as the tuning is far more affordable and gets you a much better improvement - but then I'm not you, and you may feel differently! It's simply my job to give you the *correct* info, so that the vehicle owner can then make a properly and fully informed decision based on knowing the correct facts.

And by the way - for everyone that so kindly responded to this gentlemen, please don't take any of this the wrong way or be offended - you are all to be commended for trying to be so helpful to another F-150 Online member, that is what makes F-150 Online great! We ask for any changes in gear ratio or tire size info on our custom program worksheets when we do our tuning simply to see if your speedo already needs correcting, and if so, take care of that for you - but for anyone who actually has the XCalibrator 2 and has ever actually read their Troyer Performance documentation, you will see that we point out very clearly that you can easily make your own changes to gear ratio or tire size to restore speedometer & odometer accuracy, as well as correct the shift points for automatic transmission models - and that all happens automatically by simply pressing a few buttons on the XCalibrator 2!

Though I generally do like to see gear ratio changes done in the case of 33" or larger tires, there is actually no pressing need at 33", and you will never get any increase in engine horsepower or torque by doing so - what you get is simply an increase in torque *multiplication*. Now the gear ratio change becomes more important once you get up into the 35"+ tire size range, but even then, the truth is that the vast majority (as in 99%) of our customers using 325" tires still have us do their tuning first, and then do the gear ratio change. They do that simply because it's so much cheaper to do the tuning,compared to the gear ratio change, and that way they get some very significant and immediate improvement for a lot less cost - and then do the gear ratio change once their wallet recovers a bit.

Now we DO strongly recommend doing a gear ratio change at 35"" and greater tire heights, to take the strain off of the automatic transmission or clutch in the manuals - but at anything less, you can easily do the tuning first, and that will in fact give you FAR more benefit - and also give you the ability to plug in your gear ratio change at any time after you receive the unit, that is very simple to do.

So that is the correct information, with the most important fact being that you yourself can EASILY make your own gear ratio change in the XCalibrator 2 by simply pressing a few buttons when you install your gears - taking you just a couple of minutes!

If you would like to go over this in more detail, and get the straight scoop, learn exactly what is really involved, etc., please feel free to give us a call and we'll be happy to go over all of that with you, so you will correctly *know* your various options, and what is actually involved - but the reality is, using the XCalibrator 2 as almost everyone here uses, there is no reason whatsoever to hold off on the single best bang for the buck, which is your tuning - just FYI.

Best of luck whatever you decide!

 

Great! Thanks for your input Mike. I will be in contact soon to order the XCAL2 as that is something I def. want to get. I am still going to re-gear to 4.10's but I think I will try to hold off for that after the XCAL2 since re gearing is gonna cost a grand atleast. Thanks again to everyone for the information.
