i have the same problem. There should not be a boost cut at 10psi on an r33 series 1. My mate runs 12 everyday no problems and no other mods but exhaust and fmic...

Hey Boro, Yeh, we've had this conversation before... My r33 series 1.5 cuts boost at 10 psi even with my boost controller. Now when its getting dark and the air is much cooler boosting quicker i've hit 11 and 12psi but never above this. I've also had no problems running at this boost too. So i hear series 1 cut is 10psi and series 2 is 14psi. who would have thought 3 - 4 psi extra is that much faster :cheers:

Getting my SAFCII dyno tuned tomorrow too... Will be good to get the dyno gain stats. It's currently got a tank of optimax so i'm getting a tune touch up when i start running Ultimate into it. The mechanics said they have really seen a difference between the 2 fuels.

xr8eater you cant just change the afm. You will need a computer to tune it up after you change otherwise the car will run rancid. I will have my power fc tuned hopefully within the next week or so as i wait for my turbo to come, will tell you if that fixes the missfire, if not i will try new plugs again and coilpacks.

      My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.

      I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.

      I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended

      I definitely agree with you there - I never click on content for cars I would never ever be able to get or compete with/against/be seen next to. Seeing a MX5 compete with a FD RX7 will make people upset though, for sure. Even in 2.5L Turbo form which is pretty grass roots. (or at least as grass roots as classic cars can be) Yes we're all classic car owners now.
