[QUOTE="olympic, post: 16911200, member: 168598"] I'm probably the last person who should try to read a data log but here's what stood out to me: 1) Your analog input isn't reading anything. 2) Battery voltage sags all the way down to 12.6v under load. Not terrible but maybe a big 3 wire upgrade is in order? 2)Coolant temp goes up to 210F. Probably normal with a stock thermostat but it's not helping your underhood temps. Maybe a 170 thermostat and retuned fan settings would help. 3) Your downstream air temps go all the way up to 152F during your last pull and the ECU is starting to pull timing. The 2.76 pulley makes a lot of heat and the stock intercooler system is struggling to keep up. Make sure your dyno operator has a good fan for air flow through the heat exchanger and allow plenty of cool down time between pulls. [/QUOTE]
