dyno tune or excal2
since there isnt a dyno near by i was wondering will the programs that the tuner puts in close enough for best performance or should you drive 100 miles and have the vehicle dyno tuned?i assume if you have say a spark knock the tuner uses software instead of a dyno to fix it.is this okay or is a dyno worth the trouble to drive to and have it fixed?i guess what im saying is can you get a good tune without using a dyno?

We tune many vehicles every single day without a dyno - frankly, in these heavy trucks we prefer to datalog on the road, as most dynos can't put enough load on the motor to actually properly simulate what happens when the vehicle is actually being driven, so I wouldn't be to enamored of "dyno-tuning," like it's the be-all & end-a;;l of tuning for these trucks - it's not.
Our custom tuning package includes any adjustments based on obtaining proper data, and the XCalibrator 2 can datalog everything we need to evaluate your tuning, with one exception - the A/F ratios. And if you have not done something like change the MAF meter, then your A/F's aren't going to be an issue anyway as long as the vehicle is mechanically sound - and we can tell that by all the other parameters we have you datalog.
We provide all those instructions and that capability with every XCalibrator 2 we ship.
We also even provide low-cost wideband Air/Fuel ratio testers, gauges,m etc, so you can check EVERYTHING you need without ever having to go near a dyno - so unless it's a 600+ HP beast, a dyno really isn't necessary for tuning, and certainly not for the typical F-150 owner who has a few bolt-on modifications.
The smart thing to do is not try to base your decisions on the entire Internet's opinions, and instead simply call the actual experts at our number listed below to get the real facts - give us a call & we can go over exactly what type of vehicle you have, all of it's modifications, how the vehicle is used, what you are trying to achieve (if you actually have any specific goals along those lines, and most people really don't, other than wanting more safe power), and then we can tell you up front exactly what you will and won't need to do, what's involved, exact costs to do it right, etc. that way you don't have to keep guessing - you'll *know* from experts all of that - correctly - up front - BEFORE you make any decisions.
We're happy to help you with that.
Best of luck whatever you decide,
