Twintake problems?

(1/3) > >>

Itsagthing:
Hi guys so I have had my twintake on for just over a week now and at quarter throttle and half throttle the car feels very hesitant. Anyone have ideas? The divertor is brand new for the revision and there seems to be a lot of fluttering from that too is this normal on stage 1 eddy? Cheers ollie

Scottymon:
Is this your first CAI? I find they kill some of the low end torque, but help the turbo breathe more top end.

I'd suggest putting your OEM kit back on and retesting, it may just be the characteristic of a CAI your experiencing... And hopefully your haven't dropped anything in the turbo fins.

Also check and double check any air leaks.

Can you run VCDS to check for errors and perhaps a Dyno... Rpm and MAF gs

Itsagthing:
No it's not my first and I work for Audi dealership and our vw branch is next door, I do have a feeling though that the map is not right as it was stage 1 before I bought the car, ill check it out on odis at work I just wondered if anyone had experienced any problems

You need to let it re-adapt to the new values. If you have vagcom you can reset the learning or simply pull the battery for 10 mins and that will reset the ecu. Your stage 1 map will be fine.
Before that have you checked for any fault codes or air leaks?. Sometime the seal from around the maf sensor may nkt seat right and allow air to escape giving the ecu false readings. Check all the jubilee clips etc. Failing that Id re-install the oe engine cover and see what happens.

Saintsteve:
Double check what your fuel trims are reading. Block 32.

Revision G I'm guessing you've installed?
