max boost, chip & unchip

[Sharkie]

The K04's attraction is bolt-on to what is there at the moment. Worth about 25kw ATW.

You can have a K04 (brand new) landed from the USA for AU$1200. APR upgrade to software then only AU$599. A bit cheaper than APR's upgrade kit. They should charge less for us poor Pogo owners.....

just remove the 2 hoses goin into n75 n connect up to boost controller. i bumped up d boost to 11psi and feels heaps better. but now i am chipped but still use a mbc @ 16psi.

So... Let me get this straight...

You unhook the 2 hoses going into and out of the N75 valve and connect the boost controller.. but you leave the N75 loom plug connected. Does this N75 valve feedback to the ECU at all?? Are any check engine lights thrown??

I know these engines run rich from the factory so if you fitted a controller, ran sensible boost and checked A/F conditions on a dyno to make sure everything was ok you should be fine...

I think someone (me?) should invetigate this method - I don't think too many people in Oz ahve tried this with the 1.8T (from my google research anyway!!)

It wouldn't be wise pushing it with the MBC too much as you can hit limp mode, cause the wrong fuel mixtures etc if its not done right. Your best off saving and just getting a chip/flash!

..you forgot fuel pump, possibly high-flow manifold, not to mention the rest. ..might make more sense to buy a more highly-spec'd car that has that stuff standard

Hmmm ... like Pierre says, Mark ... I'd advise caution.

Mine'll do 22~23psi and is happy.

The K03 struggles to hold more then 1.3 bar in higher gears/revs = 19-20psi
