Lol . They probley don't use 486s now , but the weber ecus where ahead of there time !a new loom is still important , but a good mapper can make a big difference .my car runs like a watch with a level 6 with pectel board ,only my 10p worth ,sonic boom didn't you have a few issue with you new ecu ? There's not a lot of people out there who can map weber to its best ?
