hmm sounds like your secondaries arent kicking in i had the same problem.
fuck all of that this is how you fix your hesitation on your t2 threads. the best way to fix hesitation on any t2 is to switch over to a s5 turbine housing or delete the twin scroll on the s4 and port match both hotside runners. i promise you the fc felt like it had the response of a bb turbo. general rule to the FC "the more you remove the faster it gets" 4b-17 http://www.rotaryheads.com/PDF/2nd_g...tems_turbo.pdf |
