oh and i am currently dyno tuned with crome

 

Make sure you're getting enough fuel, get a step or two (if you're going 100+) colder plugs, and you should be good.

I'd consult your tuner or get one just to make sure.

 

yeah, im most def getting a 255 walbro and upgraded injectors. not sure of which size yet. also, should i get it tuned again for nitrous? ive been hearing people saying not to tune it and just retard my timing a few degrees or something.

 

if you have the best tune in the car with the current setup start low 75-100 on the dyno then check your data log or a/f then work your way up. Of course u will need a colder plug. I would start the session running just a bit rich for saftey. I ran a 100 shot 4-5 bottles on a stock h22a closed deck and never blew I just cracked the ring landings in the end but it still ran with a little smoke off the nitrous.

 

so would i still have to retard my timing and everything?

 

anyone?
