Egt's don't fall as quickly after foil delete.. Why?

This may just be me watching my gauges like no other after a new mod. But it seems to me like my temps don't fall as quickly after I let off the petal. They don't get any higher than usual.. They just don't fall as fast.. Why?

foil is an insulation, underhood heat is likely heating air as it passes from intercooler to turbo... I wouldn't think it would be enough to notice, but if you're watching gauges like a hawk now, you might have just hightend your awareness more than before... however, I have to agree, since I removed the foil on my yellow truck last year, it also seems to take forever to get down to 300-350 on my EGT's before I shut it off...

I think it's just awareness. You still had one IC pipe and the whole intercooler not "foil wrapped" before.
