Good day all, sorry to ask such a stupid question but I need someone to tune my 04 350z in the atlanta area, I have put a lot of money into it and the last tune was not what I expected so I prefer not to go back to that shop.

quick overview,

Vortech supercharger
New short block, 10 : 1 pistons
crank shaft
new cams, 282 in, 272 out
cosworth plenum
heads are ported and polish

basically I replaced the entire motor, it is gen 504 at the wheel, before it was doing 546, I did drop the compression from 11:1 to 10:1 which will be a loss of power, but it should not be 40+

SO I am looking for a new tuner,

 

Were the tunes done on different dynos? Same pulley/redline?

Dynos arent configured the same, some will read lower or higher than others.

And yes a drop in compression will reduce power a bit.

Z1 motorsports is in GA.

 

^^^ Z1, ask for Jon.
It's a hike, but worth it.
