Leaving Skid Marks
Yep, spot on Aamir. I'm sure we were both surprised to see improved fuel economy with power after the tune ( including larger intercooler). I ended up going for the HDi as well.
Jarryd, if you're impressed with the car now, a TME ECU flash/tune will make you smile even more. In stock form, the factory ECU is quite an unhappy bugger, pretty much saying" argh, leave me alone. Here ya go ya bloomin greedy engine, have all the fuel ya want" and sends the signal to just dump fuel pretty much everywhere in the rev range. Hence our cars running too rich in the meaty part of the powerband, and even when you're not in it. When I had my PFL (manual) Legnum, even the dyno told the same AFR story ( too much fuel in most areas).
Steve basically gives the ECU some "special counselling". He convinces it that this is a wasteful and unappreciative attitude to have and basically tells the ECU to grow a pair when it sees you pushing the happy pedal.
So what ends up happening is that your car feels like its getting precisely the amount of fuel it needs at the given RPM range. Combine that with a few tickles of timing and more boost, everyone ends up laughing but it's safe coz' there's no laughing gas involved at all...
Not too long ago, a manual boost controller was probably the best bang for buck mod, now with the advances in tuning our cars these clever blokes have made, it has to be pretty close to being the best modification for a 6A13 on stock turbos, IMHO.
