Here is an evo we recently attempted to tune, after a pull we noticed the manifold quite hot even though the car had good a/f .

This is what happens when you have a downpipe that is too small and you get a lot of high EGTs and backpressure.

Less than before.

Turbo is some Greddy 25G 67 and the downpipe is 2in

He said it had been glowing red for some time now.

My guess is backpressure, the downpipe is just too small for the boost he is trying to run.

FYI i dont remember it glowing red when we dynoed it a month ago either.
