The only item we are unable to adjust right now is VVEL, which really has been a zero issue with basic forced induction. Now, if you want to lower the compression ratio, build the motor, or something else extreme then VVEL will be a factor but really it is a non-issue.

To my understanding, you can't throw a "Stage 3" setup that is supposed to add 60% of the stock power on a car with a high compression ratio and expect it to run great without proper tuning of timing/valves. Basic F/I is fine and understandable but how many miles do you could be logged without inevtiable issues, not leaks, but serious internal issues. Unfortunately the 37VHR is new and has not been blown and really tested that much for us to really know the limits.

The GTR is a different car. F/I from the factory and tuners seemed to take much much more interest in it than they seemed to with the 370Z/G37.
