Upgrading from a td06-20g OBX to APS SR55. Obviously quality difference but has anyone had first had experience on the 55? hows the lag?
lag is overrated...you experience it on smaller turbos, too, you just don't notice it as much because the increase in power isn't as extreme. When you're driving hard, you (should) never break below 3.5K RPM anyway, so you won't notice much of a difference at all. You'll take a little longer to hit full boost, but your talking fractions of a second, nothing that you'll really notice. The same argument applies to TMIC vs FMIC, the pipes charge so fast that you're not going to notice any difference other than the mental effect.
