Turbo is of great quality. I do however find that the springs to change in the actuator a real pain in the ***... there is so much effort needed, if anyone has a step by step DIY to make things easier please feel free to post it thanks!

need to throw my update in here. I just finished break in and starting getting into boost a little. I'm not really tuned yet, working on it slowly. But holy crap, My EF4 spools fast! Granted I'm on a built Map 2.3 liter, .040 overbore, 10:1 compression, but really surprised me how quick it would spool up. I'm looking forward to having TSCompUSA do my tune.
I just put down 447.9/500.7 (corrected) with 418./ 467.8 (corrected) torque on 31.2 pounds with my MAP built 2.0LR and EF3 (Mustang dyno)I placed 1st in the UMS Tuning time attack series setting a class record as well as placing 2nd in NASA TTU at INDE motorsports ranch in AZ this past weekend.

I believe these numbers were on a mustang dyno (approx 12% lower than dynojet)
