I would like to recommend Admintuning for Infiniti Gs and 350/470s! I have a 2013 G37 sedan journey. Mods: Admintuning Intakes, Stillen Catback, grounding kit, Stillen front and rear sway bars, Cusco strut bars, Stillen slotted rotors and metal matrix pads, Stock 17s.
Moncef, from Admintuning did my Uprev tune last week. Final tally 318whp/261tq from 266whp/230tq. Graphs attached

Initial tune done at Enginelogics. With Catback only. Crap tune .

Admintuning!!!
Also would like to add he was awesome to work with and included 4 maps. 93 octane, 91 octane, valet mode and antitheft.
My car has WOKEN UP. It is amazing the difference from 0-100!!

 

 

OP most likely went to his location since he has the dyno sheet. Moncef also does email tuning/street tune.

Nice gains OP!

 

Kinetik Motorsports.. Beltway/249

 

 

Moncef works out of multiple locations I believe because he has a day job. But he did mine at kinetik after hours for a flat fee.. $550.. also there were other people waiting in line after me, so he has a lot of referrals. Well deserved in my opinion, very nice, professional and great job. When I get the new intake plenum, Find, and SC Hes the MAN I'm calling for the retune
