This sounds like new ground to me... however, I've read reports on this site where their cars seemed slow because they were breaking it in easy... but after they got on it, it came alive very quickly.

Then again, the folks who beat on their car out the door of the dealership have always run fast.

I set the vehicle weight about 200 lbs too light because I didn't account for me in the car and I only put 3800 lbs. and I know it's a little more than that. So anyway had I added the correct weight, the horse power would read a little higher.

Straight, flat road. 3:30 in the morning so nice and cool (for Bama) and I reved to about 2000 rpm before letting off the break and getting on the gas.

Anyway, check it out. I can't wait to try it again.

I definitely wouldn't trust the hp readings, but if the time to 60 is even close, you can go ahead and take that winner sign off the lexus.

Just try running the lexus with the iphone and see what you get, so you have another datapoint.

Not sure how accurate that app is and I wouldn't put much faith in it. You want accurate times take it to the track. If any of the cars that were not running right were mine, the first thing I would do is unhook the battery and let the car sit over night. This will reset the ECU. Then drive the car around for a few days, getting on it frequently. The computer will learn this is how you drive and you should see improved performance.

I know some don't want to do this because of any fault codes being cleared but if it threw a code once it will do it again if there is some thing seriously wrong with the car.

This has become quite the interesting thread. I will eagerly await the results of your run in Bonnies car!

Did you feel any difference between the ~6 second runs and the dynolicious run?

Maybe that's the key. Maybe the computer sets a threshhonld and you just have to 'raise the ber' so to speak.

Funny you should ask that. Yes, it did seem faster. I watched the speed climb and when the run was over I KNEW it would read good. Wasn't sure what to expect but I did forget to look at the shift point out of first gear.

I haven't done any racing yet, nor any timed runs of any sort, but I definitely do not feel like this car lacks power. If I gun it, I actually feel myself getting slammed back to the seat. I'm only at ~300 miles though, and I've kept it under 4k rpm, so I can only imagine what it will be like later! So far, I am incredibly pleased

Dynolicous. If they are accurate then I'm absolutely happy with it. Not sure how accurate the numbers can be. Considering I was about 200+ pounds light on the weight I put in for the car (I put 3800 lbs.) then even the HP numbers would be about 15 to 20 higher whitch would put it in the range.

If it is just the learn thing FBodfather described I sure don't like that. My wife will drive the car more frequently and not as hard as I will. When I am in the car I don't want to get beat down by a lexus or even a Ford Mustang GT or Challenger because the car learned it is not being pushed very hard. It is a V8 with 400 HP and it should unleash that HP whenever I freakin want it to. That being said I have driven the car more aggressivley and I don't believe I have a currentl power issue. But currently I have put over 550 of the 640 miles currently on it.

Just a side note I changed the oil today reset miles per gallon and I am magically getting 17.4 over the previous 14.2. And after the oil change I really opened her up several times.

Well, that's the only common thread me an Scott seem to have. I think we babied ours too much. If I had it to do over again I'd run it wide open from the beggining. Mine seems to be possibly shaping up now that I'm full throttle all the time.

IF it's a computer 'learning' thing, it may be a threshhold deal. Where it sets to the highest level you drive at. Then it would allways be there.

I would hope that you are correct and your car was broken in according the manual and your computer learned a lower threshold. I am afraid the computer may learn the average driving habits and set itself according to those paramaters.

Imagine beating your car to redline all the time and getting max HP. Now say Bonnie drives it for a few months and gets on it some but not like you. Is the computer going to relearn her habits as it did yours for the first 1500 miles Just imagine letting someone else drive it more conservativley for a while. Is this going to be the what happens? I sure hope not and that you are more correct in it setting a threshold at the highest level driven.

I say if you ask for 400 HP the computer should give it to you regardless of what it thinks it has learned.

Not bad. Based on your 1/8th MPH, your car would have trapped ~105.3, which I think seems right.

Man it would be great if it really is just a computer thing and there was nothing wrong with the tranny or anything major like that with the L99's.
Maybe all of your testing has finally convinced you're not a grandma and it'll do sub 5.0's now.

Those guys in that vid sure make it sound accurate but I wonder how honest their being. Usually 'real' people don't throw the other comparable product on the ground. Billy Mays would have never done that.
