Default H/c nitrous question

Hi i am running 100 shot right now, i know at N/A the car is at 26 degrees, i pulled out 4 degrees of timing with the LNC-2000 and it backfires a little thru the exhaust when im at WOT and let off it, do you think i need to take more timing out now or less?

Only one way to find out...try and see That's the nice thing about the LNC unit. I'm 27 degrees timing n/a and only need 3 degrees pulled on the 100 shot

I was kinda thinking about trying 3 degrees cuz on the old system at 100 shot it ran good with only 2 degrees out but i thought it would be safer to pull 4

Best way to tell is to take a plug reading, thats the ultimate tuning tool. Do you have a wideband? Can you see if its going rich? That 2* per 50hp is kind of a general rule of thumb and is not always the case, sometimes you can run more timing than we recommend to start with, depending on each application.

As stated pull the plugs man. That's going to tell you exactly what's going on!

Backfiring through the exhaust is usually a rich condition.

What jets are you using?
