TDI TUNING

Yes but they are meaningless unless you know the rollers are accurate it's not hard to miss calibrate a set of rollers be it accidentally or deliberately.

With all due respect, that looks like a fairly optomistic rolling road extrapolation to me. Have you got a picture of before and after remap runs? That would make a more meaningful comparison. As it stands, the P-norm and P-eng figures look like utter bollocks to me.

I suspect it's a fair bit more entertaining to drive however. (c:

I see if my mate has those before figures, why do you think the P-norm and P-eng figures look bollocks?

From a starting point of 105bhp, a remap and filter aren't going to get to nearly 140bhp...... on top of that, the calculation to get power at the crank compared with power at the wheels is utter bollocks.

Not a chance!!!

The current 100's / 105's run a much smaller turbo than the previous

Tim..

They are nearly double what the stock figure is supposed to be. Normally, that's a bit tricky to do by simply altering the engine settings and changing the air filter.

Did the people who supplied the remap also do the RR session? Call me a cynical bastard but if they did, or are affiliated in any way with each other, I think that its in their interests to supply bloated figures.

For a more realistic idea of what you've gained, you'd need the before figures from the same rolling road, on the same day, under the same atmospheric conditions. You might find that the RR was fairly optomistic before and after, but you'd have the stock figure of ~105bhp to compare it to.

There's some stuff about rolling roads on here:

What was the bhp before mods on the same rollers?

The original 105bhp could be well below what the engine can actually do.

Also, it's a turbo diesel. Remap gains are known to be significant.

NOTE: nothing to do with the Seat TDI in question, just generally...

bollocks.

fabia vrs pd 130 with air filter, cupra induction hose and a remap = 185BHP.

who said it was a current one?
