optomistic rollers it looks like to me
15-20bhp out of a filter , i cant see that
before and after graphs mate, i can also get you links for the twintake making 20Hp on a ko3 stage 2 gti(k03), and 25hp on a k04 ed 30. i can then also go and show you at least 3 before and after graphs the ITG outperforming the twintake.
Dont forget though this is with a map tweak as well to utilise the intake and have all been on stage 2+ software. get yoyrself on mk5GTI.co.uk and have a look in the product reviews. plus do a search for it.
I think i recognise your name from the mk5 forum.
Ive not before and after ran my octy from the stock intake to the ITG. I already had a code red intake before swapping to the ITG, but i made a further 9HP over the code red intake.
Id agree with the roller eing optimistic if they were on differnt days, but they wereon the saqme rollers on the same day with in half hour of each other
