HELP 10% Meth mix??
Hi i am currently running 20% meth mix and a mapp on v power.The power difference between the two is approx 60hp. I wanted to run a mapp which is going to give me a power band between thesrs two, unfortunately having trouble running a lower boost map on 20% due to getting turbo creep. Anyway has anyone here run or running a 10% meth map and is this possible? And what power gain is achieved over v power by running a 10% meth? Cheers

That is defo a option worth considering, was kindoff hoping a 10% meth mix might be a cheaper way of achieving my goal if this is possible..

Its a lot of time and effort but when you see the end result its great I had serious creep issues so bad that the boost was uncontrolable in 4th and 5th gear with a decat down pipe. Once ported it holds steady.
Only thing I will say is that it may need an uprated actuator as I've had to use 70% duty on the boost controller to get 1.3bar

It would cost 150 to remove and refit turbo. Does anyone knw how much the porting would cost?? And i would also need a map tweek once turbo is refitted. Surely a 10% meth mapp would be considerably cheaper??

If your handy with spanners you could remove and refit yourself, it can be a nightmare though with the wrong tools.
I borrowed a mates compressor and die grinder and ported the turbo myself with advice from Harvey (rip) so only cost the up pipe and down pipe gaskets and time, most the time is spent making sure the finish is smooth. And the main this is not to make the wastegate hole larger than the penny

Doesn't matter whether you run 10%, 20% or no meth, you won't eradicate boost creep by changing the fuel.
Porting the exhaust housing and or increasing the size of the wastegate penny are your only options.
If you want a lower boost setting, get it ported and then remap the boost curves to suit.

In fairness, you don't need to drive everywhere at full throttle, lol.
The turbo would need removing and re-fitting and whilst it's off sent to where it was manufactured to be ported. It may be worth ringing them and seeing what they suggest and whether they'd do this free of charge.
