i can give an example of what i have tried..i will say start with the smaller tune and pull a little extra timing and read plugs..i do not run q16...

my 632 with 18 degree heads,nitrous cam ect...this tune works excellent and is a small kit to me....26n 20f...i pull down to 22degrees..5.5psi through a 73jet.

Pro Race has two nozzle options. The 90 degree will require more spread then the annulars, especially as the tunes get larger.

For 225-250 you can start with a .028N and a .022F at around 5.5 PSI and work from there. Maybe start around 18-20 degrees going down track and read plugs from there. -10 plug. If you want closer tunes and more specific numbers flowing the system can get you better tunes and more accurate HP info.. Thanks, SJ

Steve, I have what I think is the older NOS (Sportsman Fogger) with 90* nozzles. Do you have an upgraded Pill Spread Chart that you would suggest?
The Reason I ask is that the old one as far as I can tell has a 4 spread with running more fuel than Nitrous. I had 28 N 32 F 5.5psi @ 11* out with 22 total timing on C-23
I tried that and the motor is muddy when purging it. I flipped the pills and it sounded great. Any Ideas on which direction to go?

I would like to run a 250 kit for starters and step it up to 350, then a 400 kit. Any help will be greatly appriciated.

BTW this is an all aluminum 605 cu.in. Mopar with 2-4 carbs sheet metal intake, Powerglide in an Ex-pro stock truck that weights 2400 with my fat ass in it.
