Re: Which DEV upgrade? Opinions please...
Well I am happy with my DEV3HL with no unichip yet. As per the sig I have run from 138-142rwkw on various dyno's and I haven't got the JMM Race series just pacemakers.
In Sydney I get 380-420Km a tank 65-68L. Economy is Quite good still and on the highway intercaptal driving I still get 650K a tank.
The low cost interesting choice might be the DEV4 though as useless got 150rwkw with one with JMM race series and importantly no Heavt duty valve springs which makes it much cheaper and easier to install. Askk JMM about that though as I found the AU Springs pretty weak.
For an auto daily driven car the Dev3HL does idle pretty well and thats why I went for it as I didn't want to spoil the car by going too big in the cam. Most people make this mistake and I used to do it too when younger. The biggest cam may be nice for 1% of the time on the track but if you sit in traffic idling for 10% of your driving time then this might not be as much fun as you think.
I once had a chrysler by Chrysler 360 Auto that I had to knock into neutral at every set of lights as it wouldn't idle. Too big a cam!!! Just be homest with yourself about what you want and ask Brendan or Jim. They will talk to you and although I don't always believe every word they are genuinely helpful people.
