Here are four things you can do to fight the IAT battle:
1) use the stock intake
2) use the AP intake (it’s pricey)
3) if you’ve bought the MHD flasher license, flash and use performance (or track) cooling mode. It makes a noticeable difference in IAT, I’ve seen 10 degrees cooler.
4) inject more water in your meth mix. really depends on the trade offs you’re willing to deal with on this last one.
