Not sure where they’re getting all that from.

The revised engine is still producing the same power stage 1 despite the OPF (GPF) and the lack of port injection.

So I would say that when stage 3 is developed for the cars (if not already) although not road legal (as the OPF will need to be removed) It will probably produce similar numbers.

The torque and power figures I’ve seen for OPF cars have been comparible.

I’ve also seen where some owners have already removed the OPF just for stage 1 and 2. So not sure how you can say you can’t remove the OPF?

I don’t know personally, but it will require an update to the ECU software not the physical ECU itself.

I know of an owner who has swapped their standard OPF downpipe for a previous OEM downpipe without OPF from an earlier model, and then used a JB4 to bypass any issues.

My tuner told me that i have to change the entire ecu and injectors air manifold and almost everything in the car and thats my old apr downpipe wont fit in the new opf car.. but as u say there's a way to remove the opf by tuning the ecu?

I thought it was @KernelOkey who had gone stage 2 with an OPF, but sadly my memory fails me. It maybe someone else on the Facebook groups with a Cupra R ST who has gone Stage 2. But there has been others. So it is possible with a changed downpipe. If a plug in box like a JB4 is capable of doing it, then surely a proper ECU remapper should be able to do it.

Its the same engine just without MPI, so its not weaker or performing worse. Plenty of people have removed opf, either with a non opf car dp or aftermarket options. Your apr dp will fit, you just have to make the dp longer or just add a small exhaust pipe.
