:grin2: Just picked up my 2017 Mazda 3 GT with automatic. Wife made me get the Auto so she can drive it when she wants. Her car is a 2013 Nissan Leaf, that works for us because we are retired. Traded in a 2013 Infinity G37 coupe for the Mazda. I loved the Infinity but got tired of the 2 doors, and small back seat. I do miss the 330 HP and 0 to 60 in 5.0". Thus my question. Will a new performance exhaust and air intake along with a professional tune get me over 200HP? Or should I just save my money? Does anyone make a reliable turbo for the 2.5 engine? Thanks for any and all information.
