Tuning for Nitrous

[louisvanwilker]

Hey guys been tuning duramax's for a little bit here but i cant seem to get out of the low 500 hp numbers. Id like some help on where to start changing numbers to get over this goal. Plus anyone tune for nitrous? ive only run it on my 7.3 and of course i didnt write tunes for that truck. should i be changing timing big time? anyone who has some experience id greatly appreciate it.

We did an article on tuning for various chemical mods, some time back, it is on our site. But yes, you will want to reduce injection timing especially as cylinder load increases. There are substantial cylinder pressure consequences with nitrous.
