VIN# 9067
Over 2000 miles
Broke the engine in according to GM suggestions.
Oil changed @ 1500 miles

I've been really happy with this car. Wouldn't trade it for the world and it seems strong after about 65 MPH.

Engine is strong. I can feel the power pushing the heavy car but it's just not accelerating the way it should. As I've said before, Bonnies car beat me EASILY and that shouldn't happen.

WTF, You should beat her car easy ,no?
Do you think the problem is the AFM ?

That sucks, I hope you are able to get this straightened out

It is hard for me to determine how much power this car has compared to my 2007 G35 that I had, it had 306hp and good acceleration.
I am concerned with the issues that Scott,Irpq11,and rpeka are having because there might be a possibility that my car has the same issues when I try it out.
When I reach the recommended 1500 miles I am going to try the car out and let you guys know, hopefully by the end of next week. So far I have had no issues with anything on the car, so that is good. I am keeping up daily on all the threads and thanks for Scott,Irpq11,and rpeka for dilligently keepng us all informed.:clap::clap:

No issues - feels fast (probably runs mid 13s even in 90 degree South Florida heat and humidity).

Pretty much no break in. I did take it a little easy for the first 100 miles, but I did make a few high speed runs and played with the tap shifts shifting at close to redline.

0-60mph, 5.22 sec (G-tech) at 300 mile mark

Currently has 400 miles on it, and I pretty much nail the gas pedal to the floor every chance I get.
I plan on changing my oil around the 1000 mile mark.

No issues. Best run to 60 has been 5.38 (G-Tac iPhone software measured it...experimentally it was accurate +-2 MPH to my friend's speedo). Had to start it on a slight turn so I couldn't gun it till I hit the straight. I'm almost certain I could have shaved off a good chunk on a better launch situation.

So this brings me to a question for those of you having problems...try not flooring it on the launch: feed in the throttle smoothly from a stop and see if you get better results. Has anyone with problems tried this?

Irpq - the reason I say this is because...in S mode, flooring it, I got a 6.38 once. It seems faster when you feed it in smoothly, and the 2-3 times that I've measured it have borne this out.

Hell, my best time was in D mode with a bit of a rollout coming from a slight right off a stop sign.

So I'm starting to wonder if the best launch for the L99 is smoothly fed in...particularly since Mike@Newera (I think) commented that he felt that lower RPMs gave him better times as well.
