Gonna keep it tame for now. Just want to get the most out of what I've done to it without causing damage. Do you happen to have a tune that would be compatible with my CX-7?

I do not. Every car is different. I would get a hold of purple drank. for tuning. Also hit me up on facebook on cx-7 Modderz

I assume you have fuel pump internals...

I plan on upgrading the HPFP internals eventually, but for now just want to maximize performance and reliability with what I'm working with.

No! I don't think you understand the situation. If you have an upgraded turbo so the HPFP internals should be on the car BEFORE the turbo.

The HPFP is the same for both a CX-7 and Mazdaspeed3/6. The CX-7 turbo is a smaller K04. If the CS turbo is basically the same size as the MS3/6 turbo, why would the fuel pump internals need to be upgraded immediately?

The CS turbo may be the same in size as the 3/6MPS turbo if you measure it, but it actually flows a lot more air, has a different response, and so on. The CS turbo is considered a "big turbo".

Understood, makes sense. Even still, the engine could be tuned to operate at a safe level? I don't need to tune it to make 500hp at this time, I just want it to run safely within the capabilities of the existing setup. Any help with tuning the maps would be greatly appreciated. Trying to have the car driveable this weekend.

PM me with the list of mods (all of them) and the versatuner download link for your car. I can make you a safe calibration for that.
