Ive been reading all of the debates amongst tuners and have only one question remaining. Will the xcal 2 with the custom tunes for 93 octane and tuned for my headers, custom exhaust, throttle body, cai, and soon mafs, pulleys and efans give me tire shredding horsepower, I dont care about towing or anything like that I just raw nasty jerk you back in the seat horsepower .Any input is very appreciated. Thanks, James

 

They told me to expect anywhere from 20-35 HP of gain from the Xcal2 with my 2006 F150 5.4L. I guess it really depends on your truck and how it is configured before the tunes.

Of course, if you really want to jerk your head back, you should probably sell your truck and buy an American muscle car...

Or go blown.

 

Yes it will......

 

Hi Dasnuk72,

This is somewhat debated - meaning whether you will be able to "shred" the tires or not - simply because there are so many differences in F-150 configuration, gearing, tires, etc, from the factory alone that it makes the difference between some of them being able to spin the tires in stock trim, while others won't do it at all without a lot of modifications - and everything in between.

So *nobody* can make you an iron-clad guarantees on that upfront without knowing a lot more than can be discussed here.

By the way - do NOT change the MAF meter, as it does not need to be changed until the engine actually has enough modifications that it requires upgrading the fuel injectors as well - otherwise changing the MAF is a waste of money, and most aftermarket MAF's don't tune in correctly anyway, so we're very careful about which MAF's we will use or tune for. See, most aftermarket MAF's lean out the engine, as these trucks are tuned pretty rich from the factory - so leaning them out a bit will in some cases gain power, and that is how companies advertise power gains by changing the MAF. But the problem is that they throw off the MAF transfer function, and in many cases are not even properly tunable so that we can make the vehicle actually achieve the commanded A/F ratio - at any rate, for numerous reasons that are too detailed to get into here, don't change the MAF meter until the engine actually needs larger injectors, and then we have a package that includes the MAF meter, fuel injectors and the fuel pump too (they should all be upgraded at the same time in the 2003 & earlier trucks) specifically for that at a reduced price, so you would actually gain power and the additional fuel delivery capacity required when that time arrives.

The bottom line is, the best tuning available is our Troyer Performance tuning and we load our tunes into the XCalibrator 2 - so for the best possible results on that truck, you'd want us to tune it, as we have specialized in these trucks for 15 years, much longer than anyone else, and have far more R&D into their tuning. So our tuning will gain the most power.

I hope that info helps you a bit, and please feel free to give us a call to go over any of this in more detail, get a better feel for how your individual vehicle is going to respond, etc., we'll be happy to help you get the info you need.
