work done to improve exhaust flow but


just an FYI ...20g is a nice upgrade, just know that the WG flapper and the hole is waaay too small and it is impossible to bore out so you don't have a boost creep, now with my set up and on the one that i have "Super Hahns 20g" it just happened to creep to 20psi at redline which is about what I need to boost so it works out...but it is not right...only way to fix this creep issue is put on a nice external 38mm Waste-gate by drilling a hole on top through the exhaust housing...Rob at Hilton tuning discovered it while tuning my R and was able to tune nicely to the boost creep and the only reason why it worked out is my target boost of 22 psi is not lower than my 20 psi boost creep...
