done manual conv aint wired neutral switch and put bigger intercoolers on and my turbo gauge only going half what used too got code55 on ecu

Sound like a boost leak, did the intercoolers have fixing holes for the ducting? quite a common problem if these are left out as boost leaks out of the fixing holes, or you have a loose or unseated hose, the neutral switch would not have any effect on the boost level.

yup, deffo block all bolt holes on intercoolers as they can leak

do you mean where the brackets go to the intercoolers i check that 2moz. thanku. it once didnt boost up b4 and got resistor from z world and it worked knock sensor was gone seems to drive and boost up similar to then thats why thought electrics cause some1 said if neutral switch not their it adjusts timing
