what kind of car is this for? the way i test an IAT is to ohm it at room temperature resistance (u need IAT resistance specs in order to do this). an IAT is a thermistor (temp variable resistor) so resistance in the sensor will decrease as the temp increases.

also if u can view live data, u can compare the scan tool reading to the reading on an infrared thermometer. this is a more typical test with ECT sensors but i imagine it can work with an IAT, so long as u can point the thermometer at an accurate area that the sensor will pick up. NOTE: for obvious reasons, an IAT should read hotter with the hood down, unless the engine is equipped with a fenderwell setup or something.

I don't think you need meth or intercooler with a T-trim with such low boost but your air temps do seem kinda high. I have ran S-trims with 15lbs of boost and never checked the air temps for years and never had a problem, but i always ran straight race gas. I would suspect to see air temps at 194 with a OK turbo system with a low budget intercooler and work just fine. I wouldnt worry about it and don't forget to run race gas. I think a meth kit and an air to water intercooler is too much to deal with between runs. But if you do decide to put an air to air intercooler on it, you will need to crank up the boost or get a bigger blower to make up for lost of power with all the extra plumbing. This is the air to air intercooler I will using with my turbo kit and I should have air temps around 100 to 150.

Yes, I think 22 degrees of timing is too high with 91 octane, I do 24-26 degrees of total timing with 117 octane. Bring it down to 15-18 degrees with 91 or put race gas.

Mr.Freeze kit works but doesn't drop it down that low, there are better kits out there, why don't you like race gas?

I am not a fan of using 91 octane with a race car, I don't see the point.

I live in Concord, I get my gas in Vacaville, San Jose or Hayward and that's more than 20 miles away, if I want C16 for my turbo car. But if I want 100 or 110 octane for my blower car, I can get it locally at Monument Car Parts or Morgans. Where do you live?
