Looking to get this done, as in Australia, there's a company called powerchip and they send me everything i need (bar the laptop, i have to provide that myself) to install the software...
For ~£370 i can get it, i just have to send their device back when i'm done, if holden over write it they will let me borrow the equip again and update it... The software actually is modified leaving the exact same details, etc, just a different map, aparantly there's no way for the dealer to know if it's been done - hence it's appeal, the dealer is chucking a spack at me for changing the air filter!!!
What i've done so far:
Rear muffler change to alot less restrictive version
Pod filter which will be properly shielded
It's a 2.2L SRI manual, they also said, if i try it, and i don't feel the difference, i can send it back and they'll refund me!
Running 98 octane (ultimate, optimax)
stock: 108KW 203NM
"gold98": 120KW 229NM
If that produces the power it says it does, thats a pretty good increase, IMO... They also said if you have to run it on unleaded that it goes, just decreased performance.......
I need a few answers just to make me think about it
