so you bought #155 good man! i hope that you are happy with it.
XPower exhausts
Accufab throttle body or if you can afford it the Blower from Dreadnought.
I would also check to see that you ahve the orange fuel clip and the Two-Sixties uprated heater hose fitted.
Also worth changing the diff oil.
p.s. your location is blank, where in the UK are you?
