Will My Rb26 Re-tune Be Worth The Money...?

[nsta]

Hey guys, id like to retune my car in the next few months...just getting my next parts list fitted......i just need to know whether its worth me doing a re-tune for better power...and driveability...its already a great car to drive, but maybe these upgrades will help make it even nicer:)...im not really after big power now (as its a stock internal motor)

heres my current mods (running a nice 312awkw on rb26 stock motor)

Rb26 r33 gtr

R34 N1 BB Turbos

Bosch 044 intank pump

nismo 555cc injectors (running 90% d/c)

ARC cold air box, filter

stock AFM's

Stock Cooler

3" Exhaust with Aftermarket Split Dumps

aftermarket clutch

HKS Cam Gears (they have been zero-in, and not been touched with last tune)

Bleed Valve

Heres my next upgrade list for next tune:

Tomei Cams 9.15mm lift?

Bigger Injectors - 700cc?

Have my Adj Cam gears tuned

Buy an EBC for better boost control...my boost dips currenty with the bleed valve...at 5000 its 21psi...6000 its 18psi....7500 its 17psi....dips quite badly but not noticeable when driving funny enough...

Now my main question...will i be hapy with the re-tune after getting these upgrades done?...

Well ...

You wont be able to drive with different injectors without a retune/adjustment anyhow. Thats just common sense

So yes - you will need a retune regardless, and yes, you will see a difference.

A massive difference considering you had it tuned without cam gear settings, poor boost control and so on
