Bigger injectors are the way to go. But higher fuel pressure isn't an uncommon thing.
A lot of the audi/vw guys run 4bar fuel pressure. The SRT-4 guys also run 4bar from factory.

I run 150 bar in my vw =]
I didn't want to raise it too high in the 951 just because I know the fuel system is old and I didn't want to over tax anything and spring a leak, haha.

Also, the FQS will not compensate for maxed injectors. Fuel pressure can, but many say that is just a band aid for not getting bigger injectors. Which lead to my recent thread on fuel volume vs. fuel pressure.
Just wait for your MAF and injectors and tune and you will be much safer and happier.
Learn from our mistakes. lol

Also, I noticed some 996/997TT vendors selling 5 BAR regulators now. But not sure if that is to just keep stock injectors or for performance.

Sorry to highjack, but I just got my 951 recently and it has the LR 340 kit on it. Anyway, I just put a cat back on (have to smog her to register) and started looking at my A/FR and realized it's all out of whack. At WOT it's at like 14-15+ and 14-15 at normal cruising... Idle is around 12.5-13.5. I only did a couple 'light' runs at WOT to check it, avoid any damage. Problem is, today I tried hooking up a laptop to the mafterburner and the program can't find it?! (I'm hooking it up in the car) I'm dying to tune this thing in correctly, but can't log on. Any computer savvy people have any suggestions?
Also, I've searched a bit, but want to make sure.... What are my ideal ratios at idle, cruising, and WOT? Does 'cruising' include fairly high rpm driving, even though it's not wide open? Thanks for any help.
