Fg Xr6T Boost

[jacobmitchell92]

Hey guys im just wondering how much boost a stnd Fg xr6t should be putting out, iv installed a boost gauge and it seems to be going to 8psi then fading down to 5psi at the higher rev ranges and when changing gear it spikes up to 10psi for a short second is this normal?

Sounds about right to me. They usually run about 8-9psi.

I think you need a tune.

mate a tune is definitely coming soon, going to buy all the parts before I tune it, going for the Xforce 4inch dump into 3.5inch pipes dont know what injectors to go for will see what the tuner prefers and a bigger fuel pump and maybe a intercooler if I cant get into the 300rwkw

Depending on the dyno and your tuner you should be able to get around 40-50rwkw gain with just tune and injectors. If you want consistancy with your power when the weather gets warmer then a bigger intercooler is what you need. Then to reach the limit of the turbo a high flow cat or dump and cat should be able to get another 30-40rwkw. No need to change the hole exhaust as the centre and rear mufflers are straight through and provide little restriction for the factory turbo setup.

No need for a larger fuel pump unless you want to change to a bigger turbo. Some tuners may want to change valve springs as well but you'll have to see what your tuner wants.
