No it's not a new custom cam grind but rather the oil temp, coolant temp & tranny temp, in that order, that I observed while driving on the highway at approx 60 mph today in the 90+ degree heat with the A/C blasting. It's fairly obvious that FI applications do not like the heat. I already have a Dewitts radiator and a tranny cooler ( a small one but a cooler nonetheless). Prior to being FI my tranny temps rarely, if ever, exceeded 200 degrees and usually hung around 180 or so with the oil temps usually at 210 or below and coolant at or just below the 200 mark in similar heat. I also noticed less boost than usual under hard acceleration but I was told that it is normal the way my car is setup.

The unit has already been upgraded and re-built by The Vette Doctors. I certainly do not want to fry this unit.

Try Halltech's nose piece for some more direct hit air, try engine oil cooler, try custom shrouding to force air through radiator, condenser, and FMIC if you're setup that way.
Recently was having high oil temp issues, these measures really helped the high temp issues.
coolant now 178-190 plus or minus
oil temps now 194-210

Hey Spence it's really a shame that this issue isn't addressed by the FI manufacturers as this seems to be an inherrent problem with blowers. It is the main reason holding me back from going that route. To go from 185 degree tranny temps to 240 just by strapping on a blower is crazy.
