Hi, I know that mate. I did not get a new boost gauge because i fitted a larger intercooler. I wanted a more aquerate digital gauge and soon I am planning to increase the boost. I have almost all the appropriate parts to increase the boost safely, ie. 1GGTE pistons and rods, larger pulley (0.6-0.7 bar), larger injectors and soon will be getting an aftermarket ECU! I hope this will answer your questions.
