Thanks for the replies
As for the Throttle Body it's a staight fit but there's some problems when it's on the injectors shut down I think it's something to do with the potentiometer or the ECU mibbe a piggyback would work
but so far found out that remaping doesn't help...
Again thanks for the replies and if anyone can think of anything that could be causing the bigger throttle Body to shut the injectors off it will be greatly appreciated...
Oh yea it's 68mm!
Thanks
