looking into nozzle upgrades again, what size nozzles are stock and what size is best to go up to? any pro's or con's. what is right to pay? will they be ok with my psi tuning box?

Standard 110bhp manual nozzles are 0.205mm.

I would go for the Bosio or Bosch nozzles, they will give more power & less smoke than the cheap ebay variety.

If you Get Bosch nozzles, the largest i would recommend for no smoke on standard hardware are 0.216.

If you get Bosio nozzles, the largest for no smoke on standard hardware would be the 0.232 PP764/PP502.
The PP520 0.216 nozzles are also very good.

Running a tuning box with larger nozzles will just result in 'a lot' more smoke.

Without a remap, you will find that your tuning box gives more power than the nozzles alone, as it is advancing your timing by having a larger injection window.

Nozzles alone will only raise the power approx 10bhp, you will need a remap, or larger turbo/denser charge & remap for big power gains from them.

If you want to use you tuning box get relatively smaller nozzles (PP520 etc)
