With my 275s on the rear traction in 3rd isn't a problem Link to comment Share on other sites More sharing options...
Christov Member 16 Member For: 13y 3m 28d Posted 15/07/18 08:37 AM Author Share Posted 15/07/18 08:37 AM So can anyone actually answer the question. With my boost coming on earlier, am I going to require a re-tune? Link to comment Share on other sites More sharing options...

You're putting the engine under more stress with the new diff ratio so it's possible it will need a touch up. Link to comment Share on other sites More sharing options...

theking021 New Member 2 Member For: 6y 23d Gender: Male Location: Gold Coast Posted 14/12/18 12:38 AM Share Posted 14/12/18 12:38 AM Just need some advice fellas. I got a BF XR6 MKII Ute (4spd) with a 3:45 LSD in it and its starting to whine. I bought a 3:46 (wheel to wheel) from a BA XR6 Turbo 4spd. The yoke looks different and obviously brake size etc. Will my yoke fit the Turbo diff and will it just bolt in? The Turbo's run the 2 piece tailshaft and mine is running the solid. Just wanted to know before I start stripping it all apart. Any help is appreciated. Cheers Link to comment Share on other sites More sharing options...
