On the subject of timing though. When mine did make that initial 265rwkw (355rwhp), tuner said he had a very hard time going past 13* before it would start pinging horribly, I attribute it to being a very hot day (something like 37c/98f at the back of the shop), and the W2A being badly heatsoaked at the end of some 20+ dyno runs and the tuner refusing to listen to me to let it cool down. Very interesting you were at 25* with E85... how much are you on 93?
