The advantage of the AP setup is that Mazda Maniac will tune your car based on your setup. Also, you get to keep the tool, and you can use it to disable engine codes, tune the car again if you make further mods, etc. The racing beat flash s a generic flash that doesn't specifically take into account your car's setup. It's better than factory, but not as good as a complete tuning option.

As for porting templates... There's really no room to port the exhaust ports without hitting the water jackets. Also, don't expect more than 5~10HP tops out of intake porting on the renesis. It's honestly not worth the cost. Intake, exhaust, headers... nothing really adds any power to the 8 without spending a LOT of money. Mazda actually did a good job at squeezing all the reliable power out of the motor from the factory.

My car is bridge ported, AP tuned, intake, full exhaust, and I doubt I'm even pulling 220HP to the wheels (probably more like 210 tops on a good day). Compare this to guys with stock port motors that are serious racers making 200~230HP, and one could make the argument that porting does absolutely nothing for a renesis. You're looking at probably $100/1 HP on this motor.

Just giving you the info so you can make your own decision. I'm not trying to run you off, or scare you away from it if you really want it. Just want you to know that it's not like an old 13b engine where porting and good intake / exhaust can net you 20~30HP pretty easily.
