I'll definitely start monitoring those temps. Looks like you and I were running relatively the same thing. Same here though, I went past 140 after a few pulls

Would suggest you run that map.

Also can't emphasise the importance of a FMIC,

Stock FMIC is crap, can even cause timing corrections due to heatsoaking in Stage 1,

IAT'S rise rapidly on stock FMIC and takes ages for IAT's to drop.

Gotta agree with this. With my FMIC my IAT’s while driving never reach more than 10degrees above ambient and they drop during a pull usually 4-5degrees

Mhd would tell you to run stage 2, which is for those who have catless downpipes but do not have an upgraded FMIC.

Look at Arm 5" or 7"
