no one? What does choppy mean when your fuel system is fine, ignition system is fine, and your not getting any knock?

My '96 dyno'd 282rwhp and 312rwtq completely stock except for a WS6 CAI setup and a 3" cutout right before the rear axle. Nice numbers, looks like !CAT has helped those TQ numbers.

as far as the numbers they are pretty good

now getting to your other question, about the choppieness of the graph. How long since a tune up(ie. Plugs and Wires) also an opti on its way out could cause a little breakup up top like that. Are you getting any knock retard?

just a few ideas

ehh no knock retard, ignition system is all new (including opti) so is the fuel pump. Only thing i can think of are the plugs are alittle fouled cus of my dead fuel pump awhile back. PLugs and wires are 1.5 years old i think.
