2 way tune??

[Riceeater]

Is it possible to tune a PCM 2 different ways. Like do a 93 tune and then when you hit the tow/haw button have it tuned for nos?

[Riceeater]

I just thought I would have to change the timing when I use the NOS. So I can run a tune set up for NOS even when im not using it and it will be safe?

Whats the biggest dry shot I can run safely?

Cool thanks Quik!!

theres a thread on tech. that talks about this. there is a few guys running compound shots that are dry. your more limited to the internals before a dry shot should be worried. but it will increase duty cycle of injectors. so if your a stock truck on stock injectors id say 125 easily

I am new to nitrous and trying to learn but basicly what you are saying is that i can put up to a 125hp dry shot hit on my truck and still safe with out any other mods?

If you do this I would check your plugs VERY often to make sure the thing is not going lean (plugs will be light brown spotted and in some cases the electrode will be melted some).. This sounds like a dangerously large dry shot IMHO. I would not do this personaly unless you have a wideband afr guage to monitor, and/or a lean condition nitrous shutoff.

you might as well use a wet shot if you going to run a 125 shot, just my .2 its alot safer

Nice reads lots of imfo thanks again Quik

damn quik I always thought a wet shot was safer LOL nice info, I hate to jack this thread I have another question for you quik how much power will I lose without a bottle warmer, I've been running my truck without the heater, but I'm on the market for one.

Yeah allot of that is over my head but im going to keep doing research and try to learn as much as I can about it before I go nitrous.
