Big cam VE numbers Actually, my cam isn't all that big (233/235 .644/.598 112LSA) but it sure seems like it based on my VE tables. At idle (900 rpm) my VEs are in the high 20s. For instance, 800 rpm & 60 kpa, my VE is 28.6. Doesn't this seem awefully low? Seem like what a T-Rex would be.
Also, it seems that most SD Tuned VE tables model the torque curve, ie basically peaking around 4800-5200, then dropping off after that. Mine's not like that at all. It climbs until 5600, stays flat to 6000, then starts to drop after that. It's almost like my cam is installed at the wrong ICL (it was put in dot to dot). It should be in at 110ICL. Just doesn't make sense to be so lazy at low rpm and have such a late peak to the VE table.
Anyone else running a big cam that would like to share their VE numbers with me? Is mine normal or do you see something wrong with it?

send me some logs, i'll take a look at it.
i don't think you need to worry about anything, i got a few tunes that make no sense numerically, but reality speaks for itself. the cam IS big, but just in case, let me run over some other numbers
