Ive been thinking, if you have a progressive nitrous kit, wouldn'rt you need to retard the timing progressively also? Does anyone make a progressive retard box?
What I'm thinking is that if you have a 250+ shot progressive, and set the timing according to that, wouldn't it be too much at the start and possibly create a bigger chance to backfire? I know they staged timing controllers but do the have progressive?

 

Anybody care to chime in?

 

My set up consists of a timing tuner and a progressive. Don't think I need much more than that.

 

I could be wrong here but I was reading something the other day. If I understood what I was reading MSD is now making a multi step retard box.

As far as the the timming with the 250 shot. You can set the car for the set timming needed with that size shot and you will be fine.

If you do your own tuning you could set the tune up to pull more timing the higher in the rpm you got based on when you have more nitrous coming in.
