What temp does the IAT start to retard timing? I have a 1999 LS1 (currently a standard diablo tune) and was just curious at what temp readings from the IAT does the PCM start to retard timing. Normally I see IATs from 90-100* while driving in the hottest times of the afternoon. So, what temp does timing start to retard?

Awesome, so I'm not losing any potential at the 100* temps I see to be the highest when I'm cruising down the interstate.
Does the FTRA or SSRA setups help to lower the IAT temps while cruising? I did the FRA mod, but would adding either of the those help me?

i have simple free mods (hacked slp lid) and my IAT changes from 130F sitting in traffic for 10 mins, to ~90F driving around town (<50mph) to about 80F cruising at 60mph and <60F going 90mph.
anyone else got any data to compare?
