What Did You Do To Your Chevelle Today

I think for the first time out, it is running really well. I went 11.48 @ 121 the first time out with my old 2000 Z28. A dozen passes later and it was running 10.70s and trapping 4.5 more MPH. Give it time, feel it out, and it will go faster in no time. The proverbial "learning curve" of a new combination.

No, and I should have done so but never even pulled the laptop out once to make adjustments. I was making passes on my "street" transmission file which has the lockup unlocked at WOT.

I thought about it last night and wondered if it would have picked up any. I will certainly try it next time out!

The converter is a fairly pricey billet 10" 4000 stall (on the tight side). When driving around town it doesn't feel like much stall at all which is what I requested.

Did you lock yours in 2nd and 3rd or just when going into 3rd?
