Higher EGT's?

I've recently noticed slightly higher EGT's and slightly lower boost numbers. The truck seems like its lost a little performance as well. The truck has 222,000 miles and has a Superchip Tuner. At half to full throttle the EGT's rise quickly and climb to about 1200 even on the stock tune. In stock form I see about 14-15 psi. On the "tow/safe" mode I see about 15-16 psi and 1200-1300 on the EGT. On the two hotter tunes the boost numbers stay about the same and the EGT's get a little warmer. Before I would see 19-21 psi on the boost gauge and the EGT would MAX out at 1200 even on the "high performance" tune

I've read around a little bit and it seems like I may be leaking boost? The boots around the pipes going from the intercooler to the turbo are moist. The turbo still sounds good and spools up nicely and everything, so I wouldn't imagine it was the turbo. Could the boots be the problem? If so, how hard are they to replace?

the boots could be part of your problem, have you checked your up pipes?? leaking up pipes can cause the same problems you are having, shine your flashlight around them and see if you streaks of soot on them. if so you should look into replacing them with the bellowed up pipes so you can do away with that problem

boots are easy to do. undo them, replace them. sounds like you got the CCV still hooked into the air intake. at higher than idle boost they might leak. they could just use a cleaning and a reattaching but to get rid of the oil, do the CCV mod
