Weird Dyno Result Hey guys, not sure what section this belongs in...
I finally got my car Dyno'ed today, I have done a lid and filter so far. '00 TA, 298 HP 312 tg It was what I expected, but I noticed comparing my graph to the rest of the club's LS1's, that my graph was extremely up/down (jagged) compared to the others. I have noticed my car idles a little rough, but nothing to be concerned about.
Any ideas on what could the problem could be?
The person running the dyno said I should change the plugs.
Thanks for any/all advice!!

Re: Weird Dyno Result Without seeing the dyno graph, it is hard to tell.
1) Very minor ups/downs - change the smoothing on your dyno plotting software.
2) Huge ups and downs. Few possibilities - bad O2s, tires slipping on the rollers, MAF air flow readings . . . are any of a number of possibilities
3) Moderate ups/downs - could be a miss from bad coil pack/plug wire/plug or something similar.
