how much timing should i bump off my motor (b18b1 / b16 head 12.1cr) to safely run a 50? or 75? i know on a stock it's close to -2 for a 75 and 1 step colder plugs - should i even do it? lol would i be safe with like a 35 shot - or should i just dump my pistons and get like 10.5's or something..

 

Nitrous likes high compression. The higher the comp and the shot of nitrous, the more accurate your tune needs to be.

 

it's tuned to run without nitrous right now using Crome, i dont' know how i'd go about tuning it to run on spray without blowing it up and tuning at the same time.

 

you need an ems that can run nitrous. it can know when you going to use no2 and change the maps accordingly. don't know if crome does that.

 

so anyone think i can scoot by with like a 35 shot on my compression with 100 octane - or should i just buy a moates2 timer and have 2 crome programs tuned so i can run a little higher
