I'm looking for input on a few items that I am considering, and one I have installed:

Water injection - there are several kits available with various prices and features. It appears to be a good performance and reliability addon. For those who have installed one, what are your impressions? Did you use a separate tank, and if so, where did you mount it?

Turbo timer - again, many available, and all are reasonably priced. My big question is will the timer be able to continue to power the engine after the alarm system is engaged?

SSQV - I installed a recirculating SSQV setup, and don't feel it is relieving the pressure properly, regardless of the adjustment setting. I believe that it relies too much on the smaller primary valve, and that does not provide enough venting for the turbo, even at lower RPM's and boost (< 4K and 3PSI).

Thanks in advance for your input!
