New dump pipe made and fitted. FINAL dyno tune tomorrow night. Eastern Creek on Friday! WooHoo!

Update - the new dump pipe made no difference. The only remaining thing that could be causing the boost creep is the wastegate itself. I'll take the turbo off this weekend and send it off to get ported. The original company that high flowed the turbo should have done it. Grrrrr

What turbo have you got? If it is ct20b you need different turbo or somehow get an external gate - you can't port the stock one large enough to stop creep. EC main straight for instance - you are just producing too much exhaust gas at 200kmh+. And the faster you go the worse it gets.

CT26. I've been told its a common problem and shaping the leading edge of the wastegate hole as well as porting it slightly will fix it. Yes I understand that an external wastegate will also fix it though I'm trying to minimise how much money I spend on the car seeing how I have just bought a load of CF panels for it

Rory's old bonnet fitted. I'm surprised how close the colour is to my Ferrari Rossa Corso

looks good man, the colour doesnt look fifferent at all.

wtf 230kws on ct26 and 23psi....? haha what other stuff is on this car? what intercooler?

244kW thank you!
It has a PWR water to air intercooler. The heat exchanger is in front of the radiator at the front of the car and is modified from a Triumph Dolomite Sprint.

thats friggin hardcore for a ct26 lol! is that mostly from changing to E85? Where do you get the E85 from, station or barrel or something? Other than injectors and ECU, what else did you change for running the E85? Fuel rail, any fuel lines and which pump (forgive me if i missed it in the early pages/old thread)? What have you done to the turbo (highflow details?), i see your planning to port the wastegate. Interesting, i gotta do some more research into it haha

I was making 206kW on pump fuel. You do get a power gain from E85. There is a long thread about E85 elsewhere on the forum. Search for it and you will find the details.
The turbo was already high flowed when I bought the car so I don't have the details of what was done. I only know it was done by Precision Turbochargers. I just wish they had modified the wastegate at the same time..... oh well
