Here are the rolling Road results i got a few months back at the Halifax meet:

Overall i was very pleased with them. However last weekend i went with my mate to his megane meet and put mine on at the end of the day and here were the results:

Ive lost 13 bhp, what do we think has happened?
Unfortunately the last place didnt check fuelling or boost. thanks in advance
Matt

Just different rollers maybe? What you think has happened?

Ross

Normally i would say it is probably just different rollers, but the dude who did it pulled a very strange face at my graph and said its not running right and stuff but i cant really see a massive difference in the graphs apart from a power drop, Also they were the same make Rollers in both places but i suppose they cud calibrate them differently

Are you using the ebv as boost control? What mods u got?

Ross

No i have a manual controller set at 1.2 bar. also have K&N filter , superchip, de-cat ss exhaust

At halifax your boost is spiking just under 1.2 and leveling off at 0.95 bar. If it was set to 1.2 then it would spike at about 1.4 bar. On that graph it is running no more than standard boost...

Didnt someone decide that at halifax the rr was under-reading the boost though?

It was under-reading my boost lol, but who knows what my car is doing

If what youre seeing on the boost gauge on the road is different to what the graph says then believe the boost gauge.

Yeah well my boost gauge is spiking to about 1.35 bar then holding at 1.2

my boost was higher on my EBC at Halifax than it was on the graphs!

Anyone any thoughts on the 2nd graph?

hmmm, intresting.
so i can also allow my car to spike to 1.35 bar which will allow my boost to level out at 1.2bar???

dyno dynamics rollers each time, air temps could play a large part, also engine temp on the runs will factor some varience too.
wonder if the 2nd tuning company re-calibrated the rollers, holding back some power to make you want a remap.......hmmmmmm

Interesting thought karlothen. funnily enough he did start slating superchip and told me to bring it back to do a full diagnostic on it! Con artist! - well hopefully cos then my cars alright
