Yes, i looked at the build thread but never made the connection to this thread
Is it a 172 or 200PS 2.2?
The DPF is probably the most restrictive part of the exhaust - it has to be electronically deleted, as well as phisically removed, if it is only phisically removed, fault codes can be generated, the engine may even go into limp home mode
Because the DPF is the most restrictive part of the exhaust, there would be no technical advantage in replacing the rest of the exhaust with a larger bore and it may just add weight - (though the turbo may spool up a little quicker/ and it would be another thing done before you get your DPF removed, i suppose)
If the remap is done before the DPF is removed, the remap cannot take that into account/ the remap would be optomised for the car the way it was when the remap was done (the DPF still attached) (best to get all the phisical things done 1st, then the remap)
That is why its best to get the custom exhaust, phisical DPF removal and electronic DPF delete(part of the remap) + the remap, all in the same place, otherwise as the electronic DPF delete is usually part of the remap you might have to do it/ pay for it twice, or pay more than getting it done together
With a custom remap/ ss exhaust/ DPF delete, they often discuss what you want (how loud you want it/ your needs etc) do a road test, then a "before" dyno run, then fit the exhaust / remove the DPF, then they load the map , do an "after" map, then take it for another road test, to check there are no bad flat spots/ exessive smoke / problems etc - you should get a printout of the before/ after power/ torque
Though it is expensive, it all gets done at once (so you dont need to remap it twice etc) the remap is optomised for the exhaust/ DPF delete and any other phisical mods (eg - intercooler) and set up nicely
Its worth getting rid of the DPF (can give trouble in te future/ removing it helps MPG, especially regens etc, save money in the long run too)
But performance-wise the remap makes the biggest difference
Superchips are claiming 220Hp (+ 492Nm!) with the Bluefin, a remap would probably be similar thats with no phisical mods- thats probably why no-one bothers with other modifications (+ its not a RS etc )
Its a relatively big heavy car but thats a lot of power and torque and the car will be vey quick (with just the remap)
Its probably worth cleaning out the EGR/ inlet manifold, you can blank the EGR but it will generate an EML, as fas as i am aware no- one has managed to electronically delete the EGR, some just disconnect one of the wires to the EGR valve
Thats my pennies' worth anyway
Ps - i like what you have done to your car - very sleek and subtle - the wheels really suit it too
Thanks for that.
Will have a chat with the guys doing my exhaust and see if they can make a part to replace the DPF. Then when re-mapping get the part swopped and deleted.
Excuse my ignorance, but what is an EGR? How do I clean it? And why does it make a difference??
Thanks again bud.
