I'm not a professional at this subject but my understanding is tuning is done at load points/rpm/throttle position so taking the shaft out shouldn't affect it that much as your tuning the engine not the driveline, I'm open to corrections but that's how I understand it.

Wont do any harm at all, just get higher hp reading in rwd vs awd is all. As you know the removal of front driveshaft is only a temporary measure for getting the car on the dyno & awd is re-instated as soon as testing is complete. Pretty common to do this if tuner only has access to 2wd dyno or 4wd dyno shagged/unable to handle power output of vehicle being tested.

The latter case was exactly what happened with my car at Garage Tenagah when it was being done. That was ages ago now & I have had no problems. Car is great. (Gearbox not so happy atmo however..nuthin to do with tune, more to do with my drivin) :miner:

The only prob will simple disabling it electronicaly is that if something malfunctions u could end up with ur car spearing off the front of the dyno. Has happened before. JUST A HEADS UP. Much safer to simply pull the front shaft

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points?

      I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.

      Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
