Always liked the Cupra TDi, might be my next purchase after seeing this
I've tuned my 306 HDi Mr Six, the backbox mod seems quite a common thing to get the backpressure off the turbo.
My car is up from 90bhp to 150, which is a hell of a difference. Not sure how much it weighs compared to your Cupra.
Not sure I'd fancy running my daily car with no exhaust
My point is a total removal of all restriction isn't necessarily the best way to get the most power.
How long does it take for your ECU to adapt to the increased amount of air it could suck in on the Dyno?
Bonnet up, airbox lid off, cold air cascading over the intake and engine bay in general. Argue all you like, but it's good enough for me to be sticking with my standard paper filter.
I am very pleased with the car and being able to squeeze extra power like this by making cheap and easy modifications adds to the pleasure. I'm sure I'll be beaming ear to ear once it's remapped Although I fear it's a slipperly slope that'll involve an Allards hard pipe kit, Sachs clutch and hybrid turbo in a few years.
It's a slippery slope for sure
I ended up fitting an intercooler, making up all my pipework, upgrading the brakes, de-catting the exhaust, replacing the backbox with a mongoose that needed adjustment to make it fit! , replacing the interior with GTi seats (door cards are the same) purchasing two different maps for the ecu, Buying a flashing tool to flash the ecu and then replacing the clutch!
I did all the above myself at home here on the farm, Hybrid turbo and uprated clutch would be the next step along with fuel pump work, but I'm not slipping down that slope again
here on the farm
I'm sorry but in a thread about tuning diesels this made me do an LOL
Surely even if it's not dead-on accurate, the actual change in bhp/torq can be seen?
8-10mpg is pretty epic
is that using the mfa figures or old fashoned calculator way?
