try ect pwr mode if you haven't yet
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?
The 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.
