Nice work! It might feel like it's spooling slower, but you leave the peak stock power level behind shortly after you get past 3k rpm... I'd say that's spooling pretty good! Do you have a stock dyno you could overlay? I'm betting you're stronger through just about the whole range.
What's all this nonsense about needing valve springs btw? The dyno plot doesn't show him revving past the stock limiter, are there unusual failures out there I don't know about? There should be no reason to replace valve springs with a stock rev limit.
Someone said 290 is good , I seen 250 max hp. Did i miss a pic? Either way great stuff MPFAB!
Here you go! This is not quite stock as I don't have a graph from this dyno when it was 100% stock. This was intake and Anaconda with Trifecta tune in "Eco" mode.
It does need valve springs. Above 6300, knock retard spikes. No matter what I do to the tune, the noise is present. The power drops like a rock too. I'm pretty sure it's do to valve train instability.
I'll post a pull later where I reved it out past 6,300rpm
No misfiring. Car doesn't break up. The valves are floating. The drop in power is repeatable. The rpm it happens is repeatable. You don't see that with misfire. VVT tables have been extensively worked. I know what they do to power on this car. Mine are modified a good bit from stock. Nothing you do with the cams changes the 6300rpm kr issue.
Turning the boost down does fix it, but that also goes along with weak valve springs. Rpm +high boost seems to be the culprit.
