I did and I like it. There is more throttle response. The power feels smooth and crisp. I was driving on the highway, with ECT PWR switched on, you feel the power change right away. It’s like driving one of these newer Lexus’s, just like an ISF or GSF or RCF in Sports Plus mode.try ect pwr mode if you haven't yet
I'm obviously not George, but from the couple of dyno charts on his site and George confirming when I asked him directly, the tune is good for about an extra 30 hp and 30 ft lbs.Hi George. I've been following this forum post for a while and have just registered an account here to make a post. Do you happen to have any rough Dyno figures for what power and torque these cars make after tuning, and how tunable is the ECU? Can you accommodate tuning for exhaust manifolds, catless downpipes, and x-pipes?
I've seen the chart, but do you know the maximum tuning capability of the 3uz with just breathing mods (e.g. headers, X-pipe etc) at all? I know this is a tough ask, but a rough estimate on figures would be appreciated. ThanksThe chart is available at my website, which was mentioned in the thread, so it wasn't really necessary to register here to know it. And yes headers is huge improvement and it can be accounted for (they even make improvement with stock software). Even stock 1uz headers do.
