Duramax LB7 upgrades, what would you do?

That has to do with tuning.

Exactly my point.

Fully built doesn't mean dick if the power isn't there. I've seen a couple duramax's with way too much money in them not make much more power then a stock internal'd engine with a tuner.

Yeah, ive seen clint cannon's (onwer of ATS) stock engine dmax make 700hp then puke a rod, along with MANY others at that level a few years ago. even seen one after a dyno (around 800hp) on the way home completely blow the crank outta the block. If you have picked up a diesel magazine in the last year or two im sure you have seen nicks truck, it has been competing very well the last two years. But to be any kind of reliable at past 700hp on a stock dmax engine you better beef up the guts on em.

I put a k&n drop in filter in and a 4" mbrp turbo back exhaust and the diablo sport tuner should be here today! dieselsite.com sold me the exhaust and tuner, free shipping, free 5" stainless tip and received it the next day!! Thanks again guys!

K&N = bleah.


Been running my PPE Tuner on level 1 to see how much it improves the fuel economy, will maybe step it up to level 2 next month. Even with only 50 added horses its a different moshine
