    I use EFilive and also have a permanent wideband in vehicle, RJ12 cord tucks behind glovebox plugs into V2, standalone 99% of time.
    @07GTS helped me understand and tweak EOIT and SOIT, recommend him.
    With the benefit of hindsight having paid many thousands to pro tuners in Sydney, Gold Coast, Brisbane and overseas, the best thing is to get a pro tuning interface and install dual channel wideband feedback.
    Then hook up and sit beside a genuine career pro on the rollers for a day (like seven hours). This will cost about same as a set of tyres, but you end up with a worthwhile custom tune.
    You will learn a lot, have fun, and come out satisfied with the authenticity of what is possible and what has been achieved.

    This thread is doing an awesome job of convincing me to just stick with the factory tune and the money saved in the bank.

    Unless of course they are disreputable.

    I'm sort of in the same boat with the VF2 Redline we just bought. Do i take it back to the yard and mob that did the supercharger and tune and ask them to sort it, or take it somewhere else and pay to have it redone.

    Because the work was done for a car yard, it just seems like there wasn't much time spent on the tune. On cold start it nearly redlines and keeps the revs there for a while (much to the annoyance on the neighbours). It idles ok in drive (has a cam), but idles like a bucket of **** in park or neutral. Also feels like it wants to stall during gear changes at low revs .
    Worst part of all is they seem to have completely dialled out the TC, and with the torque on tap the thing wheelspins if you so much as breathe on the throttle. Sort of defeats the purpose of all that power.

    Yeah nah take it back to the yard, explain the problem, I don't think anyone would warrant much on the car in its current state of (un)tune. It is warranted through the yard, correct?

    Yep, the yard is covering the warranty on it

    There you go, fait accompli. Also I think you don't want your knowledge that the TC is "not working properly" to become a moral burden, ie may be critically dangerous under certain conditions. It really is dead easy to turn off / zero out torque management, cheap and easy way to impress. The challenge is to make it work for you for positive reasons.
    Spinning ain't winning.

    Yeah, sort of takes the fun out of it when it feels like you're driving on an oil slick. My boss's tuned GTS which has similar rwkw will still lose traction if you tried hard enough, though it doesn't give you the impression it wants to throw you into a wall each time you plant it, like the Redline does

    It took two tune revisions to get my engine running right with mods, by comparison it has taken over 30 revisions to trans, tcc and ECU torque model so it just digs in.

    Mine just digs in. 375rwkw but I think my Calais 2.9 diff ratio helps. I can make it break traction but I really have to intentionally do it. It doesn't give me any sudden surprises. Maybe the Michelin PSS help as well.

    Wow, is that NA? If so do you have a build thread?
