[QUOTE="thomas91169, post: 13194241, member: 40530"] if you inject pre-IAT then if the system fails your ECU will know it before you do and compensate. If you run a small shot and inject only for cooling purposes of the intake charge then you really don't need to retune. However if I recall, and its been a while since I tuned with methanol, you are introducing methanol particles and water which takes away oxygen from the combustion cycle, without any additional tuning you may actually lose some power since you are losing some of the energy of proper combustion. Though I think if you are doing a tiny shot for cooling purposes (so instead of your intake charge being like a 110* day itll be like driving a crisp 55* night) it doesn't effect a/f ratio or energy as compared to someone running methanol/alky injection to make up for shit 91/93 octane.
