Highest hp tunes that are reliable?

[blk450er]

I know that you can make huge power with a tuner for these diesels. What is the highest hp tune that you can run all day every day and not stress out the engine/drivetrain on a stock engine with basic exhaust/intake mods?

People run 300hp tunes as everyday drivers with those mods. Just have to drive sensibly...sometimes.

Makes me nervous, guess I would have to play it safe...

Shoot man, a stock 6.4 already has more power than my f150 5.4 with programmer, exhaust and intake. I'll be happy when i get a diesel period

Your right foot is the key to keeping your motor happy.

Once you get a tuner you will be even happier.

did i read your website right Jeff, that you can have 25 tunes with your programmer? Holy Crap!! I only have 3 for my gasser now. Man diesels are a different world

It's actually more than 25 tunes that you end up with.

I run a 300 HP tune day in and day out, only time I change the tune down is when I hook up to a heavy trailer. Running strong at 112k miles and its been tuned since 60k

The 6.4 is a slouch in stock form, but a beast with delete, tuner, cai....
