Any power graph for that gtx3071?

GT, not GTX atm. No, I changed it after I had a software for k26/27 and the turbo failed. Been modding the car/rebuilding the engine for a couple of years now. Hopefully it will be ready this year and Porkkis will make the tune late this summer or next spring.
This seems to last for ever to get ready cause of family and the fact that it´s a daily driver.

Commentary about using both 7a camshafts in a chipped AAN engine. I have to give a bit more throttle to get the car to move off from a stop. A bit more midrange & top end, I am seeing 1 more PSI on a boost gauge at full throttle. I had the camshafts from my spare 7a engine to do the swap & was changing the timing belt & valve cover gasket in the AAN engine S6 anyway. To me, not enough to warrant the expense & effort to change them out.

Gt28RS AAN cam comparison (stock v RS2 v 7a).

That´s a good comparison, but it seems, that almost no one has tested this with adjustable cam gear.
I found a couple of very interesting threads in here and just this morning adjusted my ex cam to about 5-6 degrees early. The intake is about 3 degrees early now. It starts to pull at the same as it did with stock cams(about the same, I usually just test a couple of pulls on my way to work), but now something weird happened as it stoppes pulling in 4krpm. Will test boost leakes today, cause it went a couple of times to limp mode and a couple of times the boost just dropped below 1 bar.

Update on this. Either the ecu could not handle it, or it started knocking
Either way, I took it back a little, it´s now 4,5 early leaving the intake about 1,5 degrees early. Works fine, pulls well all a way to 7krpm + and has 1 bar a little over 3k in third. I´m happy with them now

I may try to retard the intake a little, it´s just a little harder to adjust it as it´s inside the camshaft cover.
