Sorry guys - I kind of got half way through writing and had to go.
Running an e-Boost2 controler also - and the whole thing has been set up really well by the peeps at weston performance - in the absence of further ECU and fuelling mods. These are obviously the next step but funds won't allow just yet. Its been tuned to a reliable 300 (223 kw) at 0.9 bar - and with an appropriate ECU, fuel pump, Fcon etc it should make closer to 400+.
This cough thing seems to disappear after it is hot and has some high revs/boost - and sometimes it dosent happen at all. Just had new coilpacks so they're good and its not a misfire as such anyway - its like a very quick foot off the throtle and back on again. The other bloke who said he'd got this issue said that his seemed to do it at 3-4000 revs and then 5000, 6000, 7000 (on seperate climbs up the dial) and then it was clear for the rest of the run. Mine seems more hit and miss though. I was just wondering if anyone else had experienced the same thing - and if it was just a Stagea Auto transmition characteristic.
Cheers anyway guys - any ideas welcome.
John
