It would be interesting to see this graph displayed against RPM instead of speed, and also to include Torque since that is typically what you will "feel" the difference in. I'm also a bit concerned that it looks like the tuning may have been done at the expense of leaning the car out. Your air-fuel ratios get down around 12, which I personally think is a bit too lean over the long run. If those only occur occasionally at high-rpms, maybe it isn't too big of a deal, but running too lean for too long is a great way to destroy an engine. I do admire how the stock tune stays right at the 12.7 ratio pretty much all the way though... car manufacturers are notorious for tuning cars on the rich side to build in a margin of safety, but this appears to be right about the optimal line.

HA! Thanks for setting me straight on that one; been a while since I was doing tuning like this on one of my cars! And boy does your tuner sound sensitive!!! I would still love to see the torque graph versus rpm as I think a lot of people would be interested in seeing that. I think most of us are used to seeing hp and torque vs rpm on the same graph instead of just hp vs speed.

his car is legit and had been proven with gains on our local city Dynojet shop by a professional tuner.
and lastly Regarding the famous ClubLexus forum members disbelief with Quotes like"I don't believe you" or " prove it" or "Lexus ECU is untuneable" or "Uncrackble" do not stand anymore,Simply because it finally got cracked with prof in this thread.
