So I could get criticism from this post but want to know what's going on with my new car, so i bought myself a GTI this weekend that has some nice mods and is going to be my project hopefully for the next few years, 2006 55reg 3 door in Red, lowered on coilovers, coloured rear bumper, and black 18" monzas, leather and xenons, just what I wanted, it has a map on it but no idea what BHP is, after market air filter and hose to the original engine cover box so half and half and pre car delete, now the lad I bought it off gave me a diverter valve spacer/sleeve, as I wanted a little more noise from the DV I fitted it yesterday so now it dumps the air rather than recirculateing it, since installing it not only dumps the air but now makes that wowowow noise when lifting off the throttle, I love this noise but have noticed that throttle response is delayed now and the car isn't as quick, clearly the spacer isn't good for the car but I want to keep that noise, any info or ideas are welcome before I go messing around........
