2009 370z tuning question
 

hey guys i need help here,
i am about to by TOP SPEED PRO-1 Full Exhaust System for about a $1000. and thats for ( Released Resonator Silencer Design 2.75" (69mm) Exhaust Piping T304 Stainless Performance Stage 1 Package Y-Pipe + Test Pipes + Resonator Catback Exhaust with TIG Welding with 4" (102mm) Tip + Mandrel Bend Piping ) and Injen Dual Cold Air Intake System for about $500.
and i am thinking about getting the car tuned, is this good enugh upgrades for me to tune the car, because i have people telling me upgrade the fuel injectors then get the tune and i should get more power, is that true and wat kind of power should i see just from the exhast and intake, and if upgrading the fuel injectors will help to get more power from the tune what kind of power you think i can get with all the upgrades, if you have a better idea for the exhaust for a bout the same praice plz let me know thanx guys

You should not listen to anyone telling you that larger injectors are needed. I would recommend getting a tune after an intake because the pipe diameter and MAF placement interfere with the air/fuel ratio of the stock tune. I was running pretty lean with my Stillen G3 intakes and am glad I got my car tuned since it makes more power now and it is running a safe AFR.

Dont listen on the Fuel injectors, If you go with a Full bolt-on set up such as Intake/Headers/Test Pipes/Exhaust, Yes get a tune you will be most likely running lean. Even if you decide to go with any combination of the three I would get a tune.
