Ok so have worked out my issue well sort of.... Changed injectors back to stock, loaded stock tune and bam smooth idle and instant fuel at 1.8lt. Dunno y the deka 60's didn't like the fg setup?? Anyway moving on I'm looking at some deatschwerks 740cc injectors, any body used them?? Other than that im looking at the cheapest option to stay at current power level (346rwkw) and get a good idle. Thoughts??
