no sook here mate.
I don't see why a powerfc can't make an extra 60kw. I saw a Toyota Supra make an extra almost 100kw from going to a haltek (from a factory).
Its simple - Factory ECUs are tuned for 102 ron fuel, and they run like absolute shit when you put our fuel in.
They add heaps more fuel to compensate, and retard the timing because the fuel quality is so poor.
And Tezza you have absolutely NO idea.
You're running 12psi - The stock ECU's rich and retard strategy comes into play there. I lost 30rwkw when it cut in, and I have seen...I think it is 4 other R33's do the exact same thing.
And you are f**king joking yourself if you think an AFR of 14.5:1 is going to make that much power. Seriously, any tuner will laugh at the AFR and call bullshit.
I'm going off the fact that you have absolutely no idea about fueling, and tuning etc.
I can now see why some of the experienced tuners on SAU are avoiding this thread. Just a bunch of kids that threw a Sully sic big turbo\exhaust on or ran some boost and made 34987234892742 rwkw on the dyno and wonder why the guys that actually know what they are talking about call bullshit.
Seriously - 14.5:1 afrs? Thats absolute, complete utter bullshit. You keep believing that. There is simply not enough fuel in the cylinder at that AFR to make power.
not even going to comment on that one.
Care to share any time slips? I'd love to see the mph your car or your mates runs at that "power figure"
