I have a new header and shorter (more free flowing) exhaust coming very soon for sound and looks. This will mean dumping the PAV system as no boss welded into the header. Will see when this mod is done what it's like. I believe they run leaner like this once done but we'll see. I have also fitted one of those small tipped Iridium plugs and will fit the boosted electronic ignition pack I built (with switchable revert back to std) soon too.
Choke/enrichment device is shutting off; definitely!
Thanks for all the input Guys!!!!!!!
