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?
