Are you getting any codes ?? reaon i ask--that IAT sensor is a joke--I would check the reading with any scanner to see what temp it is stuck on or reading--It is supposed to read "incoming air temp"( outside temp) and adjust timing based on that--However it doesn't---What happens it reads
"underhood air temp" and that is always super high---when driving in the city its common for it to read like 160* where it has a -10* decuct in timing---these cars only run WOT at about 20* so basically it's taking 1/2 of the timing OUT----making it a real dog---LOL
Most tuners adjust the IAT table in the ECM to compensate for this false reading

Typically I will remove ALL the IAT deducts in the WOT fuel ranges
(.52 grams and up) up to 122*---- after 122* to about 167* I wil remove about 60% of the deducts from .52 grams on up-
ALSO with any air intake mod--the increased airflow can make your P/T fuel ratio lean--but the ECM will correct this usung your 02's and make the changes via your LTFT fuel trims--HOWEVER at WOT that positive fuel % additon is also transferred to your WOT fuel as well as a safety--For example if at P/T your ECM is adding 5% fuel to correct for the leaness coming fomm your intake mod---It will add that same 5% to your WOT as well !! making it pig rich and lazy--Even a 5% addition of fuel at WOT is HUGE !!

Best wy is to go to the EFILIVE website---You can download a FREE demo version from the home page which is exactly what we use-You won't be able to read ot load tunes but you can see the complete software---The IAT deduct table in EFILIVE is B5911 --Kinda hard to copy and paste so this is the esiest way to show you--
PS : most likely it's in metric so the temps are celcius--BUT go to on top left of page --click on "EDIT" then click on "configure didplay units " and it will walk you thru the rest to change all to farhenheit and Imperial (US)
