Nope that's why I'm asking.
If you want the advice of a person who has spent over 20 years building and tuning forced induction vehicles - I'll give it to you.
Go and have someone with experience DYNO tune your truck.
Most good shops will also road test after a dyno tune to make sure the results work on the road.
If you think tuning the vehicle on the road is ok - it's NOT - just a few reasons are:
- It is not very repeatable - on the dyno you can repeat the same run and/or hold the RPM at any point you want, along with any other variables you like.
- It is not very safe (you almost always have to exceed the posted speed limit, and you are almost constantly distracted from tuning by talking, watching gauges etc. - and you are distracted from tuning by driving - even as a passenger tuning a laptop)
- It is illegal (due to the fact you are going to speed and because you are distracted)
- (see above) if you get ONE ticket, it'll likely exceed the dyno tuning cost - try telling the cop you were tuning the vehicle and he'll add nice distracted driving ticket.
- It is much more likely that you will be able to catch a problem before it causes major damage if you are on a dyno.
The even greater concern is that with no prior tuning experience it is much more likely that you will do something wrong than something right.
On the other hand if you can afford (money and time/hassle wise) to "roll the dice" and learn to tune yourself then go crazy.
Just make sure you know what the risk is that you are taking - you are not talking about buying up a $3 light bulb or $50 set of speakers - you are talking about a motor with melted pistons or worse which basically means you will be buying and installing another engine, not exactly worth it for saving a few bucks on a pro tuner.
In the end, I have seen it over and over again and if you tune it yourself you will likely end up wishing you had paid to have it done - you can't exactly decide to go get it tuned after you blow up your motor...
