Ls1 bolt on's w/Nitrous, who to tune? I currently have Pacesetter Lt's/tsp oryp, no muffler, 4.10's, SLP lid on the stock pcm. I want to add a 125 shot and was wondering how to go about getting this thing tuned. Should I have frost tune it w/o the nitrous thrown in and get a hand tuner to pull timing for the shot?

Where are you located?
You can use a timing tuner like the horsepower in a box product that allows you to pull timing along with it's capabilities as a window switch and it even has a time delay for the nitrous.
LPE also has a two-step w/ timing retard function.

I'm from Toledo, Ohio there is a shop here that dyno's and tunes but they are more into the evo's and other 4g63 family car's
I will look into the horsepower in a box, Thanks!

Is it optimized?
NO
Jets are not always perfectly matched for said setup. Why? There is a 3rd element critical to combustion and that one is not metered so fuel curves need be adjusted for optimum gain and performance.

Only skilled and experienced Nitrous tuners get that involved.

I have never had to adjust my fuel curves actually on nitrous.
If you make sure your VE table is correct and within 1-2 error percentage on motor and you're commanding the correct fuel multiplier in PE then I don't see why fuel jets won't get you where you need to be.

The one good thing about a timing tuner in this case and many others is that it allows you to run full N/A timing while not spraying nitrous and allows you to pull timing while spraying nitrous.
If you have your tuner pull timing from your tune, unless you own HPT yourself or whatever program he used to pull the timing with, you won't be able to put your timing back to where it was N/A and you're stuck with nitrous timing. Is it the end of the world? No, but most people with street cars aren't driving around with their nitrous on 24/7. If it were a race car like mine then by all means use HPT like I do to pull timing and plot your own timing retard curve. 9/10 this isn't needed in a car like the OP's or most people on this site.
