Hi everyone, really hope someone can help me !

Im new here, and come from Norway, a week ago i bougth a VRS but with some problems..

Okei, can give you the specs first :

- Milltec exhaust, 3" DP with racecat

- Green filter ( have ordered BSR optiflow.)

- K04 001 turbo

- SKN chip

- FMIC

- Walbro fuelpump

- Upgraded Dumpvalve

Problems is :

Everytime i try to go fast in coners the engine power cuts, and backfire on the exhaust, not while driving straigth ahead, and just in coners and specially when going uphill ?!? So WTF ? And it´s not the ESP...

There is no new Software upgrade since the turbochange, read something about that i will need this ?

And they have just upgraded the fuelpump to a walbro one.

And when i just give it a little gas on the pedal, it says Fototototo rigth away.... ( "wastegatechatter") I have a Lancer EVO II and on that i need to floor it to get this noise, here it happens just when i tutch the gas pedal...

Hope someone understand my English or lack of it ...

Thanks

I thought you needed your mapping changed BEFORE driving with a K04 from a K03??

yea, if all they have done is put the Pump on and the turbo and not had it mapped to suite then I wouldnt drive it!

you will brake it I think.

you might find its either overboosting or putting shed lots of fuel in.

Why did they put the K04 001 in it? thats a waste of money IMO.

Hey, thanks for respons.. Ehm, i really do not now, beacose this guy i bougth it from had no idea of what he was doing..

The chip that´s in now is a SKN one , but that is for the org, Turbo, and with this fuel pump i guess it gets to mutch fuel..

So what should i do ? Take it for a remap ?

I really do not now, just want it to go like it should.

yea if pos take it there on a trailor. get it checked out too as iirc you might of cooked the pistons putting too much fuel in. pinking I think too. hopefully you are ok as the ecu will of opened the wastegate to help thats what the N75 is for I think, it tells the ecu.

but yea it will deff need a remap if things like turbo has been put on. fuel pump is not an issue but if its had a Fuel preasure regulator on it IE 4 bar rather than 3 I think it is then it def needs a remap too.

good luck mate.
