Single Turbo Boostbox Tuning

Does that thing really not make full boost 'til 5,600?

72mm turbo on 93 so it’s not going to spool as fast as a 6266. For reference on 93 6266 will hit 20 psi around 4100rpms. Now I haven’t tune spool mode or the Vanos tables yet. I can probably get that down to 5k rpms once I get the boost control figured out

Oh I figured you where on an all out fuel with a tubskie that big.
I'm working on the s366 kit and going to try and put it through full pace.

Nah on none oxygenated gas you can get about 600-650 whp before having turn on the Port Injection. It's just been raining so I haven't been able to get anymore datalogs to fixed the tune yet.

Next update I'll lower the boost target in the lower rpms because I believe that's causing PID to time out. Then worked on fixing the timing correction. I believe my bank 1 oxygen sensor is going bad because it can't keep the 11.5 afr I'm requesting and it bounce between 10.5-13.1 where bank 2 holds it steady. Might have to get my hands on some ADVs

Update. It’s been raining hard due to the tropical storm. However, I the NTK o2 sensors do not like speed tech manifold. So I’ll have to get my hands on some ADV sensors.

My buddy runs ADV sensors on his speedtech kit. @WOT808

Went ahead and order 2 adv sensors from Jeff. He has them in stock and they shipped within a day.
