    The best thing to do would be to get a Z32 AFM and go for stage 3a: http://www.h-dev.co.uk/product_info....products_id=90

    Thanks for the offer - I need a car with the H-Dev manifold

    I've noticed you're replying to messages, and thought i'd save you time, so decided to shorten my question down to one line for simplicity

    Will the 1a chip work with a bren device?

    I have a (well taped up and non-leaking) bren device, and had it setup to 1 bar, that would then tail off to 0.9 by the redline, giving me 260hp (dynoed). I then creeped it up a bit, to about 1.1 bar, dropping to 1.0 bar at the redline. It felt quicker, lets say 270hp.

    My question is, i'm interested in 1a (i already have a 1 chip off you), however i wont be purchasing an electronic boost controller. I can easily turn it to 1.2bar, and it will tail off to 1.1(ish) by the redline (it was doing this the other week with the cold air until i turned it back a notch) - it holds well for a manual controller - BUT will that be pushing the injectors too far? As its a manual controller on a stock actuator, i cant 'tell it' to go from 1.2 bar to 1.0 bar, if you get what i mean - will the injectors be going overkill at 1.1 bar at the redline?

    This, for me, would be cheaper than going to stage 2, and if i could get 285hp safely, i'd be happy what do you reckon?
    Should be ok - just make sure its not detting

    Cool - get in touch, we can get the car ready then sort out a mapping session

    LOL, missed your post, which has actually made things worse - I like quoting people

    This sounds great, I was well impressed with the old stage 1 made such a difference on & off boost. Glad to hear the new one will be ok with a Bren device.
    I'm actually running 16psi now though as you said it could take more with the FMIC & I don't set the KS -3 off (unless I hit the rev-limiter )
    Will I notice a difference just changing to your new stage 1a & going up 1psi?

    Will a stage 2a chip only work (or give more power over a normal stage 2 chip) if you have a H-dev manifold fitted?

    Not sure yet - I've not produced it.

    Hi matey.. If i send you my ECU to get the chip fitted (Taking the car off the road when mondy is sorted) can you supply me the settings that you use for the ProfecB Spec2? How much extra is it to fit? Cheers Jez...

    Is there any point me upgrading from stage 1 to 1a seeing as last time on the rollers I made 283bhp & 294lb/ft running just under 1.0 bar of boost?

    I know that peak figures aren't everything, how do the driving characteristics differ between the two maps?


    When is the stage 2a map likely to be done?

    We can fit the ECU upgrade, no probs. I can give rough settings for the profec, but each car will differ due to pipe lengths to/from solenoid, actuator etc.

    283bhp is good, but I guess that the rolling road you used was more generous than the one I used. Either way, you should get more mid range at least as you'll be able to run 1.2 bar

    The stage 2a map should be done before the end of the month

    I have a Z32 AFM too.
    My GT2871R is:
    Compressor Ind: 53.1mm Exd: 71.0mm Trim 56 A/R 0.60

    Turbine Wheel diameter 53.8mm Trim 76 0.64

    Will it work with stage 3a?
    Do I need to use forged internals?

    The 52 trim is better, but that'll be ok

    And about the forged internals? I have stock internals now.
    And I don't have tubular manifold. Can I use my stock manifold?
