Hi guys,

Here's a sample log from my GT3071R fed MS6. I did a 1-2-3 blast today to check out my latest tune. It looks like I have the boost spikes fully under control.

Holy shit, 2 bar boost, 2,8 load and 390 g/s. It's good you have a 6...

Not much then steve?

Pretty sick man, 3.0 load here we come.

I hit 3.1 in the cold. I need to get a 3.5 BAR MAP. I'm riding the limit with the fuel cut set at 1 kPa lower than the sensor's max.

I run out of flow capacity on the 3071. Whenever I have a spare $1400, I will go GTX3076.

3071 is all done by 5600

Now I figured why you were running a 8PSI map, you were in the break-in period
With these new pistons in place probably you will have to replace the turbo after a while anyway, that thin steel powder resulted in the piston/cylinder sleeve break-in period usually eats the turbo shaft up.

Btw, what are the Versatune HPFP internals? What are they based on? PTP? Or did you manufacture them using on your own specs?

That's some nice power Steve!
