Guess my main question about tuners is whether or not they make engines less reliable and less driver friendly. My bride of fifty years and I go to some remote places and camp at times.
Thanks for your input.
Ok, fist question first. Power and reliability are at opposite ends of the ruler.
Case in point, lets look at the most powerful smallest engines in the world; the top fuel engine. They put out 10,000 HP out of 500 cubes and last about 5 seconds. Now this is an extreme case so lets look at something a little more applicable to what you are trying to do.
When any diesel engine maker puts their engine in a class 5 or 6 truck they detune the engines HP. The reason is longevity. Big trucks last a long time and the manufacture wants the engines to last a long time too. Again, longevity and power are at opposite ends of the ruler.
Another reason is duty cycle. As power goes up, duty cycle comes down. It's really as simple as that.
Now, all that being said; the 7.3 is one tough and underrated engine. In other words it's the entire opposite of the Ford 6.0. With the 7.3 Ford left a lot of power on the table because they wanted this engine to run forever. And it does. With the 6.0 Ford wanted to keep up with the big boys at the time and they jacked the power level up to way power and over spec that this engine could handle.
That is why the 7.3 runs forever and the 6.0 is a hand grenade.
In short, there is no reason you can't run a moderate tune on your 7.3.
A few things to do and watch out for:
#1. Get rid of the stock exhaust and buy the biggest and most quite exhaust you can find. You want to keep your EGT down and this is one way to do it.
#2. Buy your tunes from a reputable tuner. Like all thing on the market, there are some people that know what they are doing and some that don't. Make sure you get the former.
#3. Make sure your cooling system is up to par and even over par. HP makes heat. LOTS of heat. Make sure your cooling system can handle you amount of BTU's your putting in your engine.
#4. Make sure your tranny is up to the task of taking on the extra power. (You have already done that from the looks of things)Also make sure things like U joints are in good condition.
#5. Buy a good set of gauges and know how to use them. Set limits on what your tuner recommends not what you think your engine can handle. Most likely they will be different.
Just make sure your truck is in good shape for more power and you will be in good shape.
