Some Underhood Temps I Recorded

Seems to be to many worrysome Hyper tech mentions lately. When I mod something I want it to be like that dude with the "Chicken Oven", "SET IT AND FORGET IT" I dont want to go back a few weeks later and worry about melting, leaking, smoke, whatever the case may be. Im leaving this mod alone for a while, even Jeep forum had some concerns on there.
Just my two cents, I dont get time to mod when I get the mod, let alone worry about checking the dam thing a week after the fact, so maybe just cosmetci mods are best for me for now

Hypertech uses one of the better spots in the engine compartment and assuming an idiot doesn't go crazy with a pressure sprayer under there the unit will be just fine.

I used to get nervous flashing my ecu when had the SCT and my f250. The SCT would store the factory program and write the new tune to the ecu. If something happened to the truck ecu or programmer and you couldn't restore your factory tune... Goodbye warranty. So I like the ability to just unplug it and none the wiser. Besides, I'm not looking for 1/4 mile records just better throttle response. I don't know where the jeep guy had his unit installed so the hypertech recommended location might be fine... They are ultimately responsible for testing they're unit under the hood before they offer it.I haven't read any other real issues and usually you only hear the bad and not the good online.

Fintan, I'm not moving my Interceptor because I'm worried about it melting. If you read my initial post the Hypertech unit was 14 degrees "cooler" than the outside of the fuse box it sits in and 19 degrees cooler than your exposed PCM. So my experiment proves that the Hypertech unit is completely safe in there. I however have decided to build a mount for it just so when I show off my ride people can actually SEE where the modification is. Rather than saying my tuner module is "under there". And since I am building a rad looking box for it I might as well mount it in the coolest area available.

I live in south Florida so we get heavy downpours during the hurricane season and standing water so I'm just paranoid but if people have had them a while with the same types of weather than I'm comfortable with the recommended spot. I stopped power washing engines since my 87 Iroc. Too many sensors and electronics now to worry about.
Thanks for all the info all.

Actually this is the hottest engine compartment of any car I've ever owned. It's almost completely enclosed. To give you an idea my aluminum intake manifold on my camaro SS runs cooler than just the plastic cover on the hemi. And I have unwrapped headers in there.

UPDATE: Installed 180 Degree Thermostat and ran the same test scenario. The overall engine compartment temps changed more than I expected. Changes in Bold
Exh. Manifold. 396 degrees // 390 degrees
Engine firewall 216 degrees // 198 degrees
Driver Head. 198 degrees // 187 degrees
Engine Cover.139 degrees // 119 degrees
PCM. 127 degrees // 115 degrees
fuse box 122 degrees // 112 degrees
Volant tube. 116 degrees // 103 degrees
Hypertech unit. 108 degrees // 97 degrees
Volant Air filter. 96 degrees // 94 degrees
Again these are averages over 2 days with one day (2) degrees warmer and the second day was (4) degrees cooler. Vehicle was fully warmed up, driven the same route for the same amount of time and 185 degrees at shut down compared to 204 previously.
