its an extended cab.... the hypertech made a pretty big difference in shift firmness, rev limiter can be changed to 6300 rpm ....

Thanks, 6300 rpms is perfect. Im going to go ahead and order one. Now i need to find a better intake manifold. These stock ones suck in higher rpms.

Your EC weighs just a little less than my Blazer, i wonder if i could hit low 14s with the 75 shot.
