Hey guys I have an 07 speed 3 and I recently purchased a ATP GT3076R and I have already gotten some good feedback from Mazdaspeedforums and they are saying if I plan on running under 400whp I can use my stock internals. The mods I already have are CP-e 3'' TBE, CP-e FMIC, water meth, auto tech CDFP internals, COBB AP, Mazdaspeed intake, Forge motorsports BPV and i will be ordering soon CP-e safe seal injector seals. I also have other mods suspension motor mounts etc. Anyways I was looking to see if anyone knew a good tuning company in toronto I could talk to and get some more advice. I am located in huntsville ont. Thanks!!!!
