when switching to the 749 ECM....

... im not finding anything about changing the air temp sensor..

wouldnt you have to change the sensor since boosed apps can have some really hot intake air? or does the stock one have enough range already?

To some degree it matters where you mount it.
If right at the compressor discharge, you would run at the upper end of it's limits. If you mount it in the plenum, you'll be OK.

None intercoolered with the MAT in the plenum, I think the hottest I recall has been just over 200dF.
