The next step is the box of tricks test at 30-70 and 50-70 through the gears and in 3rd, the problem is I wasn't able to get the same conditions i.e same temp, dry etc but now I have a lot more free time on my hands I'm going to let 3 tanks of Tesco 99 filter through then do a power run and then do the same with V-power until I get the same conditions to test. I'll brim both tanks just before I do them too.
I've always loved Tesco 99 but the jap boys have always filled with V-Power religously so I thought I'd try it. But 99 is cheaper and you get club card points, however, the japs boys reckon there are just too many additives in 99 which make it burn at a hotter temp and its not as good for the engine... I'm not so sure though to be honest.
I've always wanted more popping as mine certainly doesn't pop as much as others I've heard but the difference between the two petrols was amazing for that.
On the MPG front it was over mixed driving of short trips between 4-8miles and long motorway trips of 140 miles roundtrip. It is staggering though how V-Power gives more MPG. I am still running the Lohen superchips map though as its increased the rev limit and last time it was dynoed at 1320 it hit 230bhp but I'm back there for the Mini Addiction day soon so I'm going to take the map off and run standard and see what happens to both power and economy, once i've done the 30-70 & 50-70 power runs that is.
On standard map with just a CAI and powerflow cat-back and no other mods I used to average 210 miles to a tank!!
Apparently so according to my mate watching on the side lines, it was a limiter, pop, flame job, he got beatings though for not getting it on film.
