New project, need some info.

I’m not sure how to re-tune the ECU so I’ll have lower compression with the turbo. And the other big one is the turbo I am using has an internal wastegate, but there is no place on the compressor to add a line to go to the wastegate actuator. Should I drill and tap one in? the turbo came of a 2000 Volvo s80 T6, or so I’m told, when I look it up online it says it’s a 98 though, but im not worried about the year. The P/N is 9471564 and the MFD is 49131-05101. Maybe someone will know of a better place to search or can find some info on it for me, I’m at a standstill

Re-tuning your ECU will have NO effect on compression, thats down to your pistons. If you mean the turbo pressure, then wind out yhe bar on the wastegate abit.

mine didn't have a take off for the wastegate, so i drilled and tapped the compressor outlet

Thank you claymore. Thats what I was wondering..
But Dr. If I put a turbo on won't I need to retune the timing.

You will need some sort of ecu to controle the fueling and timing.

I was going to have to turbo compreser air intake go thought the stock MAF so the stock ecu would know what the air flow is, so it could adjust the fuel for more air
