I purchased a TSIO 550 Exp. from Monty Barrett,
Barrett
Performance in Tulsa,OK. He does great work at a
fair
price. My Engine was built with 8.5/1 comp and
larger
compressors on the turbos. I have 215hr.s on the
engine,
I run LOP in cruise highest CHT is 315, on climb
out on a
hot day highest CHT can get up to 370. What
