What are the signs of lifter failure? My Grandpa has a 08 Avalanche and it ticks really bad when first started until your let it idle for a while or drive it for like 5min.
If it were supercharged that number would be about 6 mpg lower. LOL
I have 2.93. The problem is superchargers love to build boost while climbing hills which sucks the fuel down.
I got over 28 mpg with no tune on my trips to Norwalk, OH with lots of town driving mixed in. I got less than 23 mpg on my all highway trip to Virginia because of hills/mountains.
^^Yep. From a MPG standpoint, I always loose a little speed going up the hills and get it back on the downhills, and get a running start at any hill you can. Most of the time I don't care enough and let cruise control do it all.
did a road trip to pick up a new to me engine. and a load of parts for it. and a literally 2 hand fulls of pcms lol
Didn't you clean the gasket surface?
