Ive got my car booked in for a remap in couple of weeks and i wondering if it would be worthme gettin an egr delete before or would it matter if i got it after. Also does a delete pipe make much difference?

before as it will fetch the engine management light on and needs mapping out .... as for the difference if its asz engine it removes the anti shudder valve ..... but it also stops the engine breathing back in exhaust gases .... how beneficial it actually is im not so sure

Any ideas as to what it does on a BLT engine?

Can't map out a blt it leaves the light on

I just blanked off the pipe/water heater from the turbo and egr,no light on and does nearly the same job

Any decent mapper can map out a blt egr delete, many people have had it done now. This rumour needs to end I think.

Also a blt egr delete will leave the anti shudder valve in place.

Really? Why do so many people say it then? Might take mine back to darkside

Because at one point I dont think it was but now people can. Shark can 100% do it.

would it be possible to put a blt egr delete and anti shudder valve on a asz?
