Out of curiosity, I'd like to compare the stock tunes.
I know there is a big difference in the VVT tables between Gen1 v Gen2.
I've attached a spreadsheet with all Speed 3 Gen1 Stock tune data.
Since we can't open maps from outside our model, if there's anybody willing to put the work into this...
Torque spikes may not be the best way to say it. Maybe instant WOT torque?
This is a good way to control load ramp and keep max torque down from early WOT (< 3K), but what if you are cruising along and then mashing it at 4k? Shit's gonna be hot and you are asking for instant max power.
I mean...
I just found this forum so I'm going to revive this to share my knowledge on prevention of this from self tuning over the years.
My technique to combat this torque spike on spool up but keep that turbo spooling as fast as possible is to stop the ignition advance from hitting like a sledge hammer...
