This morning I did the airbox Mod' (trumpet removal) on my 2003 2.2 vectra 'C' and also fitted the shorter GSI/ VXR (P/No. 9177099) cold air feed pipe to the air box as luckily my local VX dealer had one in stock @ £7.46 TradeClub price, so nice and cheap! and hopefully it's not my imagination, coz I've done something to the car, but it does seem better @ idle , not perfect but still better and power delivery also seems smoother when pressing the accelerator progressively and hence seems to have ironed out the slight hesitancy/ flatspots I could feel lower down the rev range, some have said to leave the battery disconnected for the ECU to re-learn but to be honest I thought this was pointless as I wanted to feel the immediate difference and the ECU should re-learn any different settings as time goes on as it were , in summary, nice, cheap and easy Mod'; bit awkward getting the old cold feed pipe out but got there, and the difference at the moment, appears to be noticeable!!
