Gio, i retract my statement on the gutted car. Must be a lot lighter than mine, i can't keep a transmission together lol. I went through 4 transmissions last season trapping 122-124mph. They were all P11 (strong) boxes too.
On my old log, i made 360whp on 16psi iirc. With VET cams and a 57 trim .63 housing. That was with a 91 octane tune from JWT. At 4500 ft.
I have my timing maps and maf voltage charts as well. I really don't think it is the tune, and when I had Courtney Green (look him up) look into my tune, he said he would not touch the timing map at all. He said the fuel map was a little aggressive though. It was Courtney that told me that his tune wouldn't benefit me at all, and to keep it the way it was. He liked the timing map from JWT just fine. Below 3000rpm he said he would add 2* timing with a larger turbo, but after 3000rpm he said it was all good.
I'm sure you can make 300whp on the log with stock cams. But I'll tell you this: I make 321whp on 10psi right now with 1.6 cams and the tubular manifold. To get that power with stock cams and a log, it would take about 15-16psi. The VET cams made a huge difference, and I could FEEL the VVL kick. It didn't just make noise.
Here you can see on 24psi with this 57 trim, it was making 442 and you SEE the VVL hit on the VET cams.
Blue line is VET cams 24psi, red is current setup with 13psi.
Here you can plainly see the VVL switch points, both of which you felt kick hard.
When dealing with a mass flow tune, timing all staying the same you will still feel a hefty increase of power when the cam switchover happens. You don't have to tune specifically for this. Perhaps to optimize it, timing may help. But timing staying the same you should still see that power increase from the larger cams. Because more air means more power. And the ECU will adjust to a different area on the map when the airflow increases. If airflow doesn't increase, you won't make any more power. and I believe this to be the case.
At my elevation with my setup that was very similar to Vadim's. On 91 pump it would take 16-18psi to make 300whp on the dynojet. I feel like that is too low. And it isn't a tune issue, you can't beat physics. 20psi of backpressure for 14psi of boost is about what Vadim is seeing. And 48* of overlap is causing reversion. I can guarantee you that. This is not theory at this point. I've tested it.
