So now that there's been talk of the GIAC "Clutchbuster" Tune, anyone care to elaborate their experiences with it?
Hopefully APR incorporates this as a feature with their IHI turbo tune revision forthcoming!

Muerte_x I have been running 4 gallons of e85 with a fill up. How do you blend your e40?
Nice. I would love to see logs of that. I'm not sure what an E47 tune consists of on your FSI. More timing like a water meth file or 100 octane file? Did you swap injectors? LPFP? fuel lines?
I just got done testing E25 on my TSI, E30 is next.
What do you want to know about the clutchbuster? GIAC's tune has been solid, no rev hang, and it's super responsive, even on the pump file, daily driving is great. With e85 i get worse mpg, but that's the nature of e85. Other than a couple road trips where I couldn't find e85, I've been running E40 constantly since i got the update back in April with no issues.
With e85, the car is so much faster It's crazy. I dyno'd 272whp and 350tq on a dyno that reads low. I've beat a manual stage 2 mk7 gti and have been accused of having a k04, lol. I don't know if there's a no lift shift in the tune, but when I do no lift shift it's pretty amazing. it sounds like one anyways.
I only have an intake, downpipe and lightweight wheels. i bet some more supporting mods would do that much more. It also still feels strong here in the summer where it's always well over 100 or even 110+ degrees. I've had a few races here and there that surpise me.
APR has already said they won't do anything with e85, so you're out of luck. Some cars that have e85 sensors they have developed tunes for, but don't expect it For the TSI.
Hyde, what file are you running? Any insight you can provide from your logging?
APR V3.1 93 MAP and 100 MAP with meth. The ethanol results discussed here on Stage 1 / Stage 2 stock turbo software is going to be very different from that of a K04. I suspect the K04 owners will not get to run an ethanol content as high as E40.
Exactly. I still want to see fuel rail pressure logs for Stage 1 / Stage 2 stock turbo software owners running E25-E40. For that tune there may be more headroom but for a K04 with boost right under 29-30psi peak, there is no headroom unless direct port water meth is added which "lightens the load" for the OEM fuel system.
I can try to get you some of my data later. Let me know what you want. Everything is at the shop from the Dyno runs but logs were on Eurodyne logger so I can't read it at home.
E47 but with LPFP and 135 lbs/hr injectors.
On the TSI right? which LPFP? Isn't the HPFP the issue where we max out? Or do the injectors help?
