Yes

Overall, I'm very happy with the turbo. And I'll be even happier with it after I get my boost controller and oil catch can installed (BTW: changed my mind yet again, and I'm now going to be using Prodigy's oil catch can kit, which is included with the turbo kits now - part of the reason for the price increase).

The remaining issues I have with the tune seem to be mostly limited to the engine warmup period. With the improved lower RPM performance from the Precision turbo, I can easily avoid those issues while the engine is still warming up. I still suspect an exhaust leak may be contributing to this. It's also possible that adding the boost controller will improve this a bit more. Switching to the Precision turbo, which spools more quickly at lower rpms, made some improvements to this issue. A boost controller will help the turbo spool up even quicker.

Most of the trouble I have gone through was either part of being an early adopter, or caused by my own lack of experience with installing major modifications like this. Some experience/skill/intuition in the area of getting complex aftermarket exhaust systems properly aligned and installed with no leaks would be a huge advantage. Some of the trouble I have gone through has contributed to improvements from Prodigy that everyone will benefit from. So don't let my experience scare you. Almost everything I have had trouble with can be easily avoided when purchasing a current revision of the kit (includes all improvements that have been made since I first bought mine), paying the upcharge for the Precision turbo up front, and having an experienced exhaust and performance mod installer perform the install.

Boost controller is by no means necessary. Just an easy upgrade to get even more.
