Like the title says. New with nitrous and not sure how much timing to pull from a race tune? And do I also need to increase PW? Thx for any info you can give.

With a diesel the waste gate should be backed down for N20 runs as you will drive the charger hard when the juice hits.

I used to back my WG down to 24 psi and then spray it with a .75 pill.

PW should be 3150-3300 depending on your rail psi and I never liked going over 26 degrees on fuel only, with N20 24-26 should be OK for timing.

If you do not want to change your timing use the max timing table to limit the tune to whatever you want instead of changing your timing tables.

Good Luck,

Have a spare motor ready just in case.............:hug:

On your LBZ I would run around 3300 and not drop any timing. Start around a .050 and see if the truck can handle that to start with. I like to see it pre intercooler but will work both ways with a single stage. Jeff

With a Stock motor what are the chances of going BOOM with a 70 to 100hp shot? Diesel only made 546rwhp. Thx
will start spraying in 3rd gear.
