    I agree that I would benefit, and with the switch there as my safeguard I see no reason not to put it on the list.

    You can go a set further and put a relay on the IAT sensor with a resistor. I've used a resistor that gave me -20* I think it was. Go to the IAT timing section and adjust that row to get the timing you want. That was a way to have a "nitrous" tune and a N/A tune before the COS fun.

    I have one question (maybe i missed this somewhere), why not spray the meth before the IAT sensor and get a little timing benefit? No real downside that i can see.

    That's what we do. Spray about 10-12" before IAT sensor. Use the IAT spark table to add your timing. Incase meth pump failure the IATs rise and it doesn't add the timing when it doesn't need to

    It bothers me to see 140* IATs.
    i couldn't image 200*, them pistons would be screaming bloody murder.

    I'd have to spray pre-blower to get 10-12" upstream of the blower. With those IATs it just keeps pulling timing, which drives up EGTs which I'm not measuring. RDF1 I'm guessing your IAT sensor has been relocated to the intercooler piping? I forget which year you have, but I know around 01 the trucks went to the bigger MAF with integrated IAT. On the same token, it seems spraying pre-IAT might help negate the need for the nitrous retard? You wouldn't have to pull as much from it then if any. Still a handy thing to have on hand for those tanks of shit gas you may run across.

    10-12" was just a suggestion.
    Plenty of room for atomization and all that fun stuff.

    I delete MAFs on everything haha.
    I was trying different size nozzles on my my last setup and had plugs to seal off the unused nozzles.
    But here you can see the Fbody style IAT sensor in the top of the intake manifold where the EVAP sensor use to go.

    I'm runnin a 2002 intake manifold for the cable throttle body bracket.
    I don't rem the size of the nozzles. I'd have to go look next time I'm under the hood.

    I tried near and far from the Throttle body on nozzle placement.
    This was my last setup tryin to angle the nozzle to spray at the bottom on the Throttle body.
