Outer Limits 4x4 Board

Have been looking for something to give the Patrol a little more power. All i can seem to find is products for the diesel not for the petrol.

Current specs:
1999 GU patrol, 4.5ltr petrol, auto, extractors, snorkel.

Looking for a power type chip, are they even produced?

The other thing i was looking at doing was modifying the cat for more air flow, i know some vehicles don't like this, has anyone done it on a GU?

you can get a uni chip for them (mines got one) don't know how much over stock the improvement is as i bought it with it , i did get one put onto my 97 mod 2.6ltr 4x4 courier and the difference was noticable but more noticeable was the $1100 out of my account , with my gu 4.5 im running extractors and the chip on 33" 11.5 auto and the power kicks in pretty high in the rev range , about three grand and she pulls hard but below that shes very average , (when i got the ford chipped i specifically requested it for more bottom to mid range what i got was all top end and told i need to run premium else it'll start pinging , i told them i wanted bottom mid again and they told me sorry no can do , maybe there just knobs and don't realy know what there doing , but the 4.5 seems about the same in the power curve just obliously alot more of it .

its pretty sad that the old 80 series i test drove the same time as the gu had a noticeable amount more up and go (double oh cam etc), but it still a weak yota so the gu i went
