i intalled topspeed res tes pipes on my g35 like 3months ago and am gonna install my greddy evo2 this sunday if weather permits should i reset my ecu by disconecting the neg terminal on thebattery and wil this make it perform any better???

 

cant hurt to try

 

Any time you do any installs intake, spacer or exhaust it only helps performance to disconnect the neg side of the battery for an hour or so.
Most quality instructions will mention doing just that....Good Luck & enjoy!
