Mapping/Chipping/034 Rip chip?????

If it really does 600hp, then you definitely need bigger injectors.
If you are on a budget, you can go the Siemens Deka 630cc route, but I would not really recommend them.
Better to use Bosch EV14's. This means however, that you will need electrical adapters.

The part number you want is 0 280 158 279.
You can get them in 550cc, 650cc, 750cc, 1000cc and 1700cc flavors.

I'd go for 750cc, there is no point in using too large injectors.
You will need these electrical adapters as well:

If you want to keep the stock ECU management, then for 600hp you should upgrade the MAF sensor. The stock MAF sensor is already maxed at 390hp and running 1/3 of your engine power with the ECU completely blind is a bad idea...

Don't worry about MAP sensor, I include that in remap fee.

Can also go for ASNU injectors they have ev14 internals with bosch stock electrical plugs. They're short body so would still need extension hats.

Agree, anything with EV14 cores is good

I have a set of 034 injector hats spare, though I would recommend you go for the set from finjector because they clip to the fuel rail with stock clips which makes then slightly mor secure. And they come in anodised black. Cost me about £50 shipped for the set that come with clips and filters.

Personally I'm running the Bosch 550cc EV14s with a PRJ map, estimated 430-450hp from a K26/7 hybrid, it's a fantastic car but it's eating MAF wires - I'd consider the hot film MAF upgrade especially at that power.

Yep sound advice from Ross or buy the full length ev14 from America

Brilliant. thanks for the advice.

deffo going for The ev14 injectors.

Also what MAF should i use as a upgrade????

PRJ is the only person who can advise on that really, as there's some ECU magic to be done - read This Thread Here - the RS4 MAF is bigger and thus awkward to fit, but it sounds like he's found a MAF that is the same size as stock (still needs a remap though).

Room is not really a problem now as have got a load down lower now.

Those EV14's I posted are full length.
They don't need the hat adapters at all, only electrical ones
