I have been getting quite a few questions regarding spool response of the ATP GTX2860 on the Fiesta ST.
I just finished up a customer with this turbo unmodified as it comes from ATP, a pumaspeed exhaust manifold along with all the bolt-ons.
Maximizing spool via tuning in 65F ambient temperatures and in 4th gear we have 20psi right around the 3700 RPM mark and 26psi by 3900 RPM.
For the size it is quite a responsive internally gated turbo - hopefully this clears up what to expect from the ATP kit.
