Right put them back in and i think i found the problem, took the car round the block to check it and my boost normaly peaks at 30ppsi then drops right of to about 23psi......not now put me foot down in 4th and it went round to about 35psi before i noticed and lifted off before i done any damage so i went home and turned the boost back down to what it was after a few runs down the road till i got it right and now the boost does not drop off as much so i have had a boost leak all this time

Next question what boost can i safely run on grays?????? car revs to about 7500rpm just in case this helps

was only setup a few month back but he did not turn the boost up past 30psi as he said the turbo was ringing its neck but it seems this has been due to the leak......but on the day we checked all the pipes and manifold and could not find any leaks, don't even know were it was leaking as i have only had the plugs and injectors out...
