Hi, folks had a jabba induction kit on my LC for a month or so now and i swear that its running a little lean now and power seems down between 3k and 4k revs. Was told that an Audi 4 bar fuel reg will help, but cant find one. Anyone know where to get one and what 2 pay approx? Cheers
Heard that the downpipe is really really restrictive on the cupra aswell. Is that true?

4bar fpr will do more harm than good if the mapping is not adjusted to suit

why do you think its running lean?

uprated downpipe is a very good mod (ive had a 2.5" milltek turbo back previously)

just seems since ive fitted the filter to be a little flat in mid range and just seems to me like a lack of fuel causing the problem. What u reckon it could be otherwise mate?
How much did u pay for the miltec downpipe?
Cheers

Do a TB reset if you have vag-com it's easy takes about 2 minutes,

If not remove battery cable for 10 minutes, then reconnect, there should be a whiring from under the bonnet, don't turn on ignition then your good to go.

If you do a search there's loads of info on this..

This might help, http://www.seatcupra.net/forums/showthread.php?t=135892

could be any number of things, if it was running lean the car would tell you (epc light on dash)

open cone induction kit? any heat shielding? any cold air feed?

milltek price is on awesome gti site :)
