eh...yea ok what you said......:whistle: if the eml light was on then there defo a problem i wouldnt say the d/v spring was the main issue...what codes did vag-com give you.??

cant remember the code it gave now

something to do with air iirc "the wiizard" will be able to confirm this as he hooked his vagcom on it for me today

i werent sure if the spring would effect the dump valve so thought id just see peoples opinions on it as most seem to use green or yellow

although i tried a split-r today and the boost issue was the same

gonna phone revo tomorrow and just clarify what was done to it
judging by the other mods my car has i do think it would have been mapped, as previous owner told me to ring revo and give them the reg number as he had lost the paperwork

then i guess its leave it to the professionals

It could be a case of somthing really simple. Just a guess but check all your fuses under your steering wheel and the ones on your battery to make sure they all ok.

See if you can find out what the code was and post it up will give us somthing to go on and get you to the problem much faster.

ill find the code out for you

a few things to add, i have a blue spring in my 007p and i have a "j" n75 valve too which after a search here has had its faults before, but i have tried 2 of them

i wouldnt have thought the spring would be at fault as i tried a split-r on mine and it did the same

im going to ring revo tomorrow and check a few things with them

then im going to contact stealth racing i think to get this sorted

Could be the n75 valve then...could try swaping it out with yours if your nearby and try un plug the maf and see if that makes any difference...

Check the hoses for leaks again the one coming off the egr valve has split on a few peoples cars giving this same fault.

hey mate, sorry i've not been watching the thread...

The code that came up was the SAI: Incorrect flow detected. Has it come back on yet?

light hasnt come back on yet mate

after you left i managed to open my 007p and it has blue spring

although i spoke to forge motorsport and they said it shouldnt matter, they told me to look elsewhere for the problem i have

they offered to send me a new spring too lol

i tried 2 of my own n75 valves which were J valves and the problem still occured

ive read about certain problems with these n75j valves

could it be worth trying an n75f if i buy a new one?

Yea id revert back to the standard n75 to give it a try see if it makes any diference...

To save just buying one though...if wiizards one is standard n75 then see if you can do a quick swap with his and see if its the same... :)

Update:

Had the car over at mine today, tried changing the settings with an SPS3, but the car doesn't seem to recognise it. Tried it in mine to check it was working, and after a few seconds i got the beep. But in Bergs car no beep:think:

I can assume from this the car doesn't have a REVO remap???
It has AMD stickers inside the door sills, but would an AMD map only hit 15 psi??

The car drives fine and feels like it's running stage 1 with soft settings. No sound of boost leaks or hesitation.

Thanks for your help today mate ;)

I will be in contact with AMD tomorrow to find out if they can tell me if my car has been mapped by them or not, and what has been done, hopefully they can

If this is the case then the guy i bought it from has pretty much lied about everything lol

but ill be happy to know if my car is running normal or not

That's ok mate, think your cars running fine tbh, see waht AMD say, proabably one of their maps.

S1l3NC3R has a stage 1 AMD map, maybe he can shed some light?

I take it your waiting for me then..:lol:

Well my AMD map boosts upto 1.4 bar so about 20 psi.

15psi does sound low for a stage 1 tbh.

Just out of interest have you checked the boost gauge and piping for any leaks or faults etc..??

some logs of actual vs requested boost etc would be a big help.
