n2o and n/a tuning....
n2o and n/a tuning.... ok guys.pretty soon im going to a TNT F2 nitrous system.and over time ill end up going to a BIG shot.also ill end up doing a LOT more mods. now,im looking into running an AutoTap, or EFI-live(or similar)....what all do i need to make this happen? obviously i need a laptop,right?also how hard is it to get my head into this kind of tuning?im an electrician(for 7 yrs now),so i figure i have a pretty good deal of common sense.but is this easy stuff to catch on to? what are my bare minimum requirements to make this happen.thanks guys...from a tuning newb. 
Also i did some searching and it looks like HPtuners is the way to go.

Bare Minimums: Need a laptop (I run an old IBM Thinkpad 350Mhz laptop as my primary logging and tune on the fly laptop)
Then you need a scanner and tuning solution... HPT (HP Tuners) is available now and is the by far the best solution available .. for the 499 you get 2 vehicle types (year and model locked not vin locked) , the scanner includes bidirectional controls (so you can change certain items on the fly in realtime via the laptop)
Tuning can seem difficult at first... but it just takes time... describing how to tune is hard... easier to ask specific questions ... but basically from what I've found... you want to run as much timing as you can before knock (find the knock point and then go a couple degrees below) and you want to run as lean as is safe (lean = power.. but too lean = blown up ****) ... I would suggest downloading the HP Tuners (www.hptuners.com) help file from their website and looking through it... last time I printed it it was 36 pages or so I think... but gives you an excellent idea on what is available to modify in the PCM
As for N20 (kudos for using the correct abbreviation ... lots seem to refer to it as NO2 for some reason .. 2/3s Oxygen would be nice.. but Nitrous Oxide is only 1/3 Oxygen) i've heard for every 50 horsepower pull back 1-2 (2 safer) degrees of timing (I haven't been keeping up on the nitrous stuff... need to get my car running right on motor first)
Also don't fret about the lack of responses... it's a saturday night (well now sunday morning) so not alot of people browsing this section heh .. i'm sure others will respond with insight/feedback

HP tuner is the best !
it offers everything you need in one package. I purchased it when it first became available and the more I learn about tuning the more I realize that HP tuners in the best program out there.

People that run nitrous on the street. Do they just run a nitrous/rich tune all the time or is there some other trick that people use?

I would rely on the stock tables for fueling (I was running a dry kit, didn't have WB or anything at that time though)
for a small dry shot (100 or less) the stock tables are prolly fine for fueling (I'd still pull timing out but lots don't even do that) ... for a wet shot or direct port you can control fueling w/the jets so no need to touch the PCM for fueling

so is it quick enough, that if you pull up to a lil '04 Stang,you can flip the tune quick enough to smoke his ***!lol!
i also have a timing tuner...so i just basically have to see if my AFR is good and check for KR.
