Modding gm iat sensor
Has anyone ever tried modding the gm open element iat sensor before? I've been trying to chase down my heatsoak issues when a friend pointed out that the iat sensor is sitting in a chunk of brass that is most likely heat soaking by itself. So I ordered myself a spare sensor, grabbed the dremel and 4min later voila, bare sensor ready to epoxy into a nylon fitting! The sensor is just swaged in the fitting; no glue. Easy and clean.
I have yet to do the gluing so no in car results. I will try to do some back to back logs to see if there is any difference but I fail to see how this could hurt.

My sensor is mounted just after the cold side exit of the ic. I'm running a diypnp and am seeing heatsoak and having hot restart problems even with it there...

No, nothing like that. Im having issues with my iats going way too high after hard pulls. I know the root of the problem (boost leak/turbo working too hard) but what confuses me is how long the iats take to come back down to normal. Say during a pull my iats will go from 90 to 140, after the pull the reading will take 15-20sec to come back down to normal, in fact on the graph the down slope looks almost identical to the up slope during the pull. Honestly im not sure if this is normal as this is my first turbo vehicle, but Id think that as soon as you get off boost the temp of the air leaving the turbo should come down to normal pretty quick. I am also getting bad lean restart issues during the hot humid days.
