Sorry for the delay Ive been outside and done the following :-

1). Adjusted cam timing back to where it was before setup (i.e. its now slightly retarded compared to where it was - turned dizzy anticlock just under 1mm - there was a punch mark for the previous setting).

2). Removed the bleed valve that was added am now back to standard boost.

Checked TPS, is clicking OK, tested with meter, seems to be switching OK too. I dont think there is a problem with this as there is a noticable "lurch" when the throttle totally shuts (as there always has been).

Been out for a test run and it "seems" to be popping slightly less, also seems OK when on boost (upto 8psi with amal switched off). Still having the odd backfire when amal valve is back in and boost peaks at 11psi. Checked coil, primary 1.2 ohms, secondary 7.6K ohms (slightly high coampared to Haynes?). Volt drop to from battery to coil +ve 0.2v at idle, nearlt 0.5v at high revs. Probably going to order a grp A from Mike R to see if this can solve the misfire.

As for pinking, this "noise" seems to be when you floor it at low revs off boost. It does sound like pinking (using my mums Renault which contantly pinks as a reference!!) but it could just be the exhaust creaking and me suffering from RS paranoia. Could it pink "off boost" at low (2-3K) revs?. As mentioned previously it should be fuelling more than it use to as it was turned up so I cant understand why it would be pinking and "lean popping" now its back to how it was pre setup apart from the EMFPR settings??.

Any ideas anyone? (cheers for the offer Stu bu the way )

Cheers,
