Yeah, That mod is no good if you've maxed out the injectors.
Not common on a stock ECU though. Stick a multi meter on the injectors and check the duty cycle.

Another option is a rising rate fuel pressure regulator, once again if you haven't maxed out the injectors.

What have you done about the MAP sensor?? Being only a 1bar sensor what does it do under boost??

Another option you could investigate is using a 2bar MAP sensor of a Starlet GT (provided they both have a 0-1.5v range) and some bigger injectors, as the scale the MAP sensor uses is different. This could get messy though.

Check out the article on Autospeed.com.au "DIY Bigger squiters" I think it is called.

How does the Rolla go compared to your old GSR??
