You could say that about any modification or power level? You could say that about any modification and/or power level? I believe Rob's own ute is running over 500 on E85 with standard internals. Yes 400 is quite a lot, however if you go through the 400 section of this forum and others there are FG's from Xtreme, Pit Lane, RDP, CV, Profile Auto Sports, Elite, CMS etc.. all have cars out of their shop running 400 or more with standard internals.. Tune as we know is the important factor and the one that the OP has posted up looks very reasonable to me. Ben
