If your IATs are very high, such as in the case of running more boost, the gains will be even higher.
Generally the kits are set with either a boost activated signal, or a MAF activated signal, either of which works depending on your goal. The nice thing about the MAF controllers is you can typically slope the methanol injection to rise with more airflow so it doesn't spike too rich down low, or run leaner than you want up top. However some just prefer the keep it simple stupid method of setting a boost amount where it comes on and not having to do anything as its super simple, always works, and tends to be very consistent. The MAF controllers are best dialed in with a wideband air fuel meter connected to see which amount does what, and where it benefits, but ideally you would want both kits on a dyno, although ive installed at least half without either and had no issue, it just requires driving and testing.
As far as install, its 4 wires... power, ground, pump output and MAF trigger / Hobbs switch trigger. Most of the install time comes from either figuring out where to mount the meth tank, where to tap the line in (unless you have a charge pipe setup already), or if you do them how I like to, tap the factory windshield washer tank for methanol so when youre low, the factory "low washer fluid" light comes on. Methanol is basically cold climate washer fluid anyway, so it works fine for windshields, and as long as the washer fluid youre buying is 50/50 mix of water/meth and doesn't have any added detergents, it can be used as methanol for your engine as well, although id personally advise just buying automotive fuel grade methanol from a reputable dealer, or summit racing has it for cheap with free shipping over $100.

Great post! The high lighted part is exactly why I wont go with meth and highly recommend E85 or Racefuel.Meth Pump failure+ advanced timing means formula for motor failure. Syonara N55 engine!
I took my AEM meth kit off my racecar and will be selling it. Meth is old school tech but many still use and swear by it. Not meeeeee!

I don't really have any power goals to hit and actually love the way my car performs simply with FBO (my FTP charge pipe has the nozzle bung for spraying meth) and Stage 2 BM3 tune.
I definitely like the idea of a MAF/MAP activated signal for progressive control. So based on your information, I think the Snow Performance Stage 2 would be sufficient which has this capability. Have you installed SP WMI kits before? If so how was your experience? If not what brand do you prefer to work with and why?
Thanks again for the input.

Why not just tune your car for E85 and also have a racefuel map? Its safer and will make the same and or more power?
I have had 2 tuners tell me to take the kit off because they did not like tuning with it. FenixMike's post is the only one I have found that has broke this truth down that I have seen.
