as it says, is there any "standard" for what stage your car is for the mods done, or do you just make it up?? ;)

I've got a pdf file from Stillen that lists them all but can't find anywhere to upload it at the moment.

Providing the fuelling is correct all throughout the rev range, higher boost levels are okay, running 17-18psi meself using bigger turbo's and other mods.

Oh and why is there no mention of fitting Cybercarfts shiny bits and bobs to increase the level, not fair :D :D

smithy:cool:

Well with any luck ill be running 20psi now its all done, just so long as its all done correctly.

Will have to wait and see how long before Boom lmao again.

so have you lot who run at high boost levels got NOS fitted?

Nope. Although I had 555 injectors and JWT turbos when I ran it at 20+psi ..... bang went the engine! I won't be doing that again.
