I had the pure 900 turbos installed downpipes and black boost intakes,made 690 wheel hp on 98 octane and was happy with the performance did a best time of 5.97 sec 100-200km per hour with old tyres.
after a while i felt it did not perform good anymore and there where a lot of faultcodes.
had them all cleared and the car went better again.
Last week the check engine light went on also had that deleted and now it comes back on again.
the guy that cleares the faultcodes says the problem is with the mapping of the car.
The performance is also not what it used to be again.
Im tired of letting the codes cleared and they keep comming back.
what should i do?

Talk to whoever tuned it for you. That shouldn't happen. Maybe there is other issues, ask the tuner to investigate.

What codes are you getting? Just clearing them without addressing the reason why they are coming up will not solve anything.

Ok thx guys
there were a load of codes he cleared them all to see if some codes came back.
i think i might have had some bad fuel in it because i put some new fuel in the other day and after a while the check engine light did not come again.
gonna do some draggy times 100-200 to see what it says

I notice these weird misfire noises went away after I switched from Mobil to Shell.

Im in belgium and went from total 98back to shell98,im gonna put shell 98 back in it from now on and keep an eye on it

You had the TCU tuned as well, right? I know these cars will pull power and be unhappy with aftermarket turbos and higher power numbers if the TCU isn't tuned.

Do you have anyway of data logging ?

Im still without my car,yes they did some logging and said for some reason it was not making the boost it should do.
i also have the blackboost intakes has anyone had issues with aftermarket air intakes?
because they want to change it to the original intakes and see what that does

I have pure 900 with modalworks intake. Not a single problem for 30k miles with all these mods. Some of the issues I can only speculate, fueling, spark plugs and ignition coils need to be change after modding. The tune itself is not good. Who is your tuner?

My tuner is in belgium im not gonna say who it is for now.
but im getting frustrated its been 6 weeks and i want my car back only done 3000 km so have not driven much.
My car is at another garage they installed the turbos etc.
they checked the plugs,coil pack boost leak and i think some sensor.
Im gonna give them my intakes tomorrow but i dont see how that can be the issue

Have you done any fueling mods? Hard to diagnose the problem without data. Need to know if the car is running lean, or rich, or timing is off.

There is no way an intake would stop a car making boost. IMO your tuner is clutching at straws, cut the rope and move on.
Happy to put you in touch with our tuner if you are interested (Morendi)

Thx but my options are limited,im located in belgium and there are not many tuners here in fact this one is one of the most known tuners

All we need is a laptop and internet

They have put in the stock map and had a code for the sensor of the intake,the cable was not connected right in the sensor so hopefully that will be it

Does your car only have 3000 from new? Or since you modified it? That would be one hell of a
mod to a brand new car - awesome. Can I ask what tyres you are running on to get traction with that kind of power? Do you mainly track or drive on roads?

Only 3000 km since the mods.
I got goodyear eagle f1 tyres not so much traction but i only drive on the road no track.
but my car is fixed so im happy,im gonna pick it up in the afternoon,my tuner i cant fault the dyno testing i didnt have to pay and he does a good job.
the garage that put the turbos on and where i dropped the car off to fix it i was not so happy with but they said they were gonna make a good price for it.
so that makes up for some off my frustrations.
The problem was the cable from the intakes to the sensor was not connected right,a friend of mine had that removed some time ago and probably rushed it a bit when putting it back on.
anyway thx for the replys here
