I've used DP+ will BP Ultimate derv & it was like using rocket fuel
Pick up was noticable & the chug chug tractor sound was a little less on tick over.
I just use normal derv now & a dose of DP+, trying to cut my spends down a little.
You can get it from FLETCHERS in brum http://www.oscott.co.uk/fletchersautostore/
