Been looking at the bluefin units for stage1 anyone running this?

Yep.....

No complaints

Did u notice a massive difference mate? If I'm spending decent money I don't want to be disappointed, what's it like power delivery wise ? Cheers

Last 100,000km no issues.

 

Big boost in torque & driveability.  Good fuel economy. 

 

Great bang for buck but you'll get more from a more specialised tune - more money though.

Had mine for 25000 miles stage 2 this year only £50 more certainly a much better car for it
