So finally my car is good to go! Ended up swapping in a stock 2nd hand low KM (miles for you guys) motor and continued on, currently running no air filter, waiting for turboguard to come. It was tappering off at 340-350KW~ and 6000-6500rpm and I told the tuners to rip off the air filter off as I've seen many others running without one and it's super restrictive, then boom, just over 400KW at the wheels (approx 550HP) without pushing etc.. I asked them to leave it there and not push any further.

I feel my boost levels are a bit low though, I've got the internals upgraded to the Si trim, running the stillen 9lb pulley, so was expecting around 12-13psi~? After a while I'll think about changing some pulleys and going more, right now I'm running 1050idx injectors and don't really want to start changing more again, already had to upgrade the 340 pump, went to a 525 so I could go next stage if needed.

It was making about 325KW on pump fuel and 6500RPM. All in all changing to e85 gained the peak power + 10-15% through-out the rev range, loving the extra power, on Nitto invo's in top of 3rd gear it starts to lose traction.
