Proven Performance
Tuned by MK Performance on a K20-powered MR2 using our first-priority manifold:

“With a 4psi base spring, we hit 15psi using 96% boost controller duty. Swapped to a 7psi spring and pushed to 17psi, hitting 93% injector duty on 1000cc injectors. Took it to Devil Developments for a dyno run and laid down an incredible 519.3BHP at just 17psi—with zero boost creep.”
