    I'm in as long as we go to the ridge! We could even stay at the casino out there if we wanted to make an entire day of it.

    Seconded. The ridge is FANTASTIC.

    While tracing the source of an oil leak, we discovered an engine mount was broken which weíre addressing now.

If anyone has any suggestions for stiffer replacements Iíd greatly appreciate it.
    Can anyone identify what this cracked bracket is? My inclination is this is due to engine movement under hard on-off acceleration, any other theories before I replace the bracket and install stiffer engine mounts?

    Issue 8 - Oil Leak (APR 2014)
    I noticed early this month the undertray had a significant amount of wetness accumulated on it and that the valve cover had a fresh stream of oil running down it after driving around. After spending a couple hours removing the diffuser and undertray ensuring the oil-pan and lines were good to go, I've located the source of leak which I originally attributed to a faulty oil cap. Turns out it was a cracked valve cover. I'll swing by the Ford dealership this week for a replacement unless Noblerine can hook me up with everything in a one-stop shop...

    The culprit.

    Front motor mount.

    Moved fuel gauge (APR2014)
    While changing out my console for an M400 one and customizing some switches in preparation for some impending tuning, I found myself killing multiple birds with one stone courtesy of the Good-Idea Fairy. Unable to move the oil pressure/temp gauge into the second spot in my console bezel due to solder and/or sensor removal issues I decided to move my fuel gauge into the open spot thus accomplishing three tasks: filling the hole and completing the console (no stray holes to fill), making it easier to see how soon I need to refuel, and making way for an HVAC vent for my right hand in the former fuel gauge spot (a gripe I've had for some time). The whole project only cost me about $20, two beers, and a couple hours of time. There's still a gasket behind it I didn't remove so it doesn't sit flush yet, but I'll fix that in the future.

    What do the anti lag, turbo boost, and silver toggle switch do?

    The turbo boost button will activate a second map on the ECU which will increase boost from stock to around 20 PSI. The Anti-lag will change the map again and spool the turbos up early for better launches and decreased turbo-lag. The silver toggle I haven't come up with a use for yet, but I'm working on it! I can't post anything yet because the tune isn't complete, I'm waiting on new valve springs before we up the boost. You all will be the first to see it when it's done!

    Anti-lag

    Unless you have some unusual intake and exhaust hardware, anti-lag is really just drastically retarding the timing and adding extra fuel when you lift off the throttle for shifts. Massive retard means that combustion is still happening while the exhaust valve is open. Energy from rapidly expanding exhaust gases that would normally push the piston down is now headed for the turbine. The extra fuel means that combustion can (and usually does AFAIK) occur in the exhaust manifold.

    Remember that this all happened because you closed the throttle for a shift. Without anti-lag, closed throttle means much, much less exhaust gas flow through the turbine section of the turbo. Less flow means the turbine slows down, which means that the compressor side is also slowing down. When you jump back on the gas after a shift, exhaust gas flow increases, causing the turbine and compressor wheels to spin faster, and turbo starts making boost again. But that increase in turbine/compressor wheel rpm (aka spooling) takes time, maybe as much as a second or so. That is lag, and when not much happens for the first second after a shift, you realize that a second can feel like a long time.

    With anti-lag programming to increase exhaust flow to the turbine during a shift, the turbine slows down quite a bit less than without anti-lag, thus the compressor does not take as long to begin making boost when you get back on the throttle.

    You might imagine that moving combustion out of the cylinder and into the exhaust system would be hard on the exhaust system. You'd be right.
