So far there are whispers of fueling problems (and Livernois is reportedly looking into this). Whether the stock system is literally out of capacity, or whether the ECU is throttling the system (cutting the throttle/turning off injectors, etc.) to stay within safe boundaries (prevent detonation, safeguard the transmission) has not been publicly/firmly established with repeatable logging. EBB uses a Boost-A-Pump on his Flex. 4DR Mike set up an aux fueling system to increase capacity for the HP (700+ AWHP) he was trying to achieve.Until the system flow capacity is proven to be a problem, I'd look at the tune tables to make sure that all the i's are dotted and t's crossed for the conditions the vehicle is expected to encounter. This is a problem you run into in computer programming all the time, you have to handle all cases, however you choose to do it. Maybe in this case the full throttle scenario has not been fully tested before implementation.Why would they be out of fuel on 2013 when they have more fuel available than 2010-12?Why wasn't that caught in the development process?Any 2013 Torrie tunes having the issue?

Definitely keep an eye on the AFR before and after. What octane are you running (and I am presuming E10)? Maybe the combustion is too hot? Maybe the E-85 cools it to an appropriate temperature? Which would lead to a colder spark plug discussion/solution. If we could monitor the flame front, that would provide valuable data too.

The car downshifts to 1st and sometimes when the power hits everything briefly shuts down. (adding E-85 seems to fix it) I will be sure to note what RPM that would be next time I am out.
