Took my 03 G35C up to CIN Motorsports in Charlotte, NC. These guys are great! Very professional, friendly and very knowledgeable. I live in Raleigh and i'm glad i took the 3 hour trip to them (past a couple local osiris dealers). Had them install new spark plugs and Dyno tune me. During the install they noticed some loose bolts around my plenum and tighten them all up not to mention gave dead on estimates for price and time. They've got one of the cleanest shops I've seen with a bunch of very impressive builds in progress... if you're near them i'd go just to look around haha, great guys to talk to as well. Great price, i can't say enough good things about them! i'll be headed back to pick up their exhaust with in the year too for sure, it sounds amazing.

For those curious... my mods are JWT Pop Charger, Stillen Z Tube, 5/16" MD Plenum spacer and test pipes. My baseline was 248hp/238tq after CIN Tune 266hp/252tq. Definitely runs a lot smoother and my gas mileage went from 21.8 to 27.2 on the way home. They gave me great advice of where i can go to get more out of it and where my weak links were. They've done tons of R&D on our cars and own and drive very nice looking Gs! More of a passion than a job for these guys.

My GF tagged along and told me after looking around my car was lame if it didn't have atleast 400hp... i nodded shamefully in agreement. So i'll definitely be back Ben! And please take some videos of the final dyno's of those builds you're working on, very interested to see how they turn out!

 

Wow sounds great. Cant wait to stop by there when I have time.
