Hey fellas,
Just looking at getting some advice and maybe some reassurance from some of you guys who are running Stg 1 or above.
My car is an S3 S-tronic, just over a year old, recently serviced and as far as I can tell, in good health. I decided to take the plunge and fit a Neuspeed P-flo CAI and was pleased with the results. Lots of sucking noises and a small amount of DV on lift off.....all good. I then ordered a Shark Stg 1 map and STS and installed the performance map. I went for a spin and noticed that (other than a big performance increase) when the revs are going through the 3-4k rpm range, I get a sort of flutter noise. It's like lots of small DV noises that happen really fast (psst psst psst psst). I must stress that this is while I am still accelerating, not on lift off.
I've contacted Shark and they confirm they have issued the correct map for the S-tronic and have suggested it could be a characteristic of the P-flo. My worry is that there is a leak somewhere and I could be causing damage to the turbo if it is some sort of surge.
Has anyone else on here found the same results after a remap with a P-flo fitted, or indeed any other CAI? I plan on taking the P-flo off and re-fitting the standard engine cover/air box to see if the noise is still there.
It'd be great if someone could share a little advice on anything I could do to check for problems. I have checked for codes using the STS and found nothing.
Cheers in advance fellas
