Of course it's better to not scale if not needed but if you have much WHP, the oem 4.2 housing is too small.
I mentioned speed density since we wouldn't need scaling at all if that was available. Up to 4.2 MAF, no need for scaling. Above 4.2 MAF limit, use speed density without MAF.
You are making claims without any sort of support. I have cars over 600whp on the 4.2 housing. What do I do for cars over 600? I run an 85mm HPX setup. |

I was a bit unclear. I Think you missunderstood me. What I meant was that up to the limit of 4.2maf in oem 4.2 housing there is no need to scale since it's better to buy a MAF matching Power goal and as the top one buy the 4.2 v8. If you want more and especially much more than the 4.2 can support it would be nice with speed-density. But as you say there are alterantives when going beyond 4.2 v8 like hpx. |

So I boost leak tested the car and no leaks. Can I blow my car up yet!!! Urghhh
Next I'm taking off this external waste hate to make sure the valve is seating properly. Can I boost this big turbo with stock timing tables? I feel as if I should have no problem building at least 10psi but 2psi?

I would consider retarding timing a bit at peak torque, then adding it back in bit by bit, but that's me. |

Because you have no idea what you are doing and are blindly stumbling around in a dark room, filled with glass. You are going to slip and break something. |

If you get a big enough turbo you may be able to overcome a boost leak. It would require pressurizing the entire atmosphere however, so plan for a very large one.

Okay, so I logged throttle position and it only goes to 35%. Why is this? It's cutting load by using the throttle. I'm guessing this is because I have no maf yet?

I HAVE BOOST!!! LIFE WITH BOOST!!
After hours and hours I started from square one, I just added a huge turbo to the car! so boost isn't going to come on till 4000 rpms so throttle plate angle might be out of wack and pids are going crazy. So I played with a couple maps and sadly I had to change a safety map. So now it's time to learn these maps and get the full meaning behind them.
KFVPDKLD-Max pressure ratio (throttle plate) for ldra diagnosis - Max. zulässiges Druckverhältnis DK für ldra Diagnose
KFMSNWDK-Map for scaled mass flow over throttle valve
KFWDKMSN Map for target throttle angle
