Ponder this, the 6637 will raise temps maybe 10-20* over stock system . . . that doesn't explain 200* increase in EGT's.

Your intercooler/rad cleaned lately?

At idle my IAT will jump higher and faster than the stock box did, but once moving the air temp is only 0-10*F higher than the stock box was.

Did you leave the IAT (intake air temp) sensor plugged in? That's really the only sensor around there that you should have messed with. No way you should be seeing that big of a EGT increase though.
