    Have you tried putting the car on a dyno this will give you a very good idea as to what's going on the trick is finding a dyno technician that can read result correctly.

    This was a fairly old thread I probably shouldn't have resurrected, oh well..

    I've seen several cars running trs msb stage one maps and never seen any egt issue's, granted they were all auto.
    I do wonder if you had some kind of restriction/cooling performance problem with the intercooler, the other thing on my mind is that the engine actually needed a rebuild before you got it, and as such you were just feeding it more fuel to overcome the performance deficiency, hence causing the high egt numbers, I Believe you also stated that why was worse in fourth than fifth?
    This could also be due to air passing too quickly through the intercooler and not allowing it time too cool, pointing to an intercooler issue, I'd need too see logs to see air flow to diagnose this though, but if it is the case, you are risking your new engine also,
    And lastly, it could all be the trs manual remap as I said, I haven't seen that particular one in action.
