i just got done delivering a boat with no problems. now i hook up to another boat to ship n have some issues.
1st boat:
cruise 70 mph
ex temp 650-850
eng temp 180
boost 8psi
avg 12-14 mpg

2nd boat: just a hair bigger
70 mph
ex temp 1000-1200
eng temp 200-210
boost 18-26psi
avg 8-11mpg


whats going on here????? its been like this for the last 1500 miles.

it will hold 34psi boost no problem

 

Any smoke with those temps? I just had a small boost leak at an intercooler boot that just about KOed the truck,if you have a lot of fuel and a boost leak you will deffinetly know it.
