Hi folks just been browsing threw ebay as we all do and spotted this AUDI A3 A4 A6 A8 TT TURBO BOOST CONTROLLER GAUGE KIT 2 on eBay (end time 11-Oct-10 16:25:11 BST) ive got a 1998 a3 1.8t totally standard, Do u think its worth me getting a boost controller just to tweak the power a little till i get some serious money to spend on her? Just one more thing does any one no wot the standard boost pressure is on these engines and how much can you turn this up by safely?
