Been about 6months so far since I last asked about this. In that time I've swapped Heads and fixed all boost leaks. So even after all of that im still only managing 10.6mpg. Fuel Injectors Balanced.
Now to help out here's what I haven't changed yet. Fuel Filter, shims on the head (valve tick), and cold start injector. I can't think of what would cause me to get this bad of milage, and im not racing around everywhere. The mods on the car are as follows 3" Exhaust, Intake, 20G Turbo, Boost controller (5psi Low, 11psi High).
For my cooling question, ever since I swapped heads, and did a coolant flush, the car takes forever to warm up. Even after letting the car idle for 10min and driving it for another 15 it still isn't at full operating temp (going by the stock gauge). My guess is maybe the guage sender sensor is going out? Or maybe a wire? Or could it be my fan clutch is working to well (if that's possible). I've had the fan clutch on my car for about 7 1/2 months now and only above 60mph (like on the freeway) does it disengage (gets quiet). On cool nights on my way home from work; outside temp is 58'F, I can hear the fan "wooshing" at 40mph with the windows up. Now maybe im not used to having a new fan clutch but im so used to having a quiet one. However even after having it on the car for 7 1/2 months its still really tight when cold, you can't get it to spin if at all, tapping it will only move it less than an inch. Maybe this also attributes to my bad milage?
So is there such a thing as over-cooling? Or is the sensor on the t-stat housing bad? As far as I can tell the gauge still works its just really slow.
Help would be appreciated
