egt ?

Alright put the chip in tonight and I have stage 1 single shots and the 120 race tune. When I get on the skinny peddle it got hot quick. I saw 1200 and got out of it. Turned the chip back down to 65dd and egt's are fine. I got a 4" dp out of a wrecked truck and it had a few ding in it and I deleted the muffler. Would me getting a full 4" + exhaust help bring those temps down or is this just normal on the race tunes? I appreciate the advice just don't wanna waste money.
