I just got my flywheel resurfaced and used a spec 1 since I am not turbo/supercharger my car anytime soon.
I kept the butterfly's because most people do I believe. I dont want to lose tq and when I get tuned those will kick in differently I believe.
Update: I didnt fix the check engine light. I changed the fuse and it didnt end up working. I guess I will troubleshoot more.
