6600 is pretty high, man. I feel like my engine is screaming at 6000. Are our stock rods engineered to handle those kind of revs? I'd hate to see parts start flying out of that thing
You may want to dyno a couple different times with different chips in the PCM. That way you can pick which powerband you prefer, thus figuring out where your ideal shift points should be. If you're willing to spend the money at the dyno shop, do it right. Use the info to help achieve your optimum tune, instead of trying to show up on the dyno with huge numbers right off the bat.
Still, for lack of a better word, I'm quite proud that you're flying the flag for the NA crowd. With the increased timing of those chips, you may just beat my estimates for your car. Please, stop torturing us. Take it to the dyno ASAP.
