I got my Takumi exhaust system installed today and a custom downpipe made by Tim’s custom exhaust here in Coon Rapids MN. Today is the first time I drove the car for 30minutes on the freeway. Here is the video for A/F ratio traveling at 65mph. The second A/F ratio during idle. Are these normal A/F ratio?
Thanks

AFR's look fine cruising (im assuming you're not in boost on the 65mph vid) and look fine at idle.

what are they in boost?

At 10 psi A/F ratio is flat out at 10 and I cannot read anything lower.

13PSI Spring installed and boosted. It feels like 350WHP+ even with AFR at 10.

I received this in the mail today from Tweak's Performance

The stock ecu will make the car run pig rich in boost! Lean it out to 11:1 A/F and watch how much harder it will pull.

Your idle and cruise A/F is very stable, right were they need to be.

It is scheduled for dyno and tune next month.

I decided to go with less horse power turbo for easy control and tuning. This is my new Precision CEA 6266:

Broooooooooad inspiration man I have my 92 sc300 5spd looking to do the swap for the same reasons newer technology and just a fresher motor. Bro your swap came out real nice bro.. As for down pipe which down pipe you used? I'm retaining my w58 until I can source a r154 or may go with the cd009 350z box . I was also thinking to run stock twins first because this would be my first boosted car

It so much easier to remove the stock twins without the engine in the bay....If your budget enables you to go single right away....I would strongly recommend it.

CatManD3W is right about this. It took me over 4hrs to remove the stock twins with the engine on the stand. It is a lot easier to upgrade the transmission later if decided to go for more HP.

She is on the dyno for more than 3hrs because the engine spit/cut out at about 5200rpm. It cannot go above that rpm at all. We changed the spark plug to NGK 4644 but it doesn't do anything. She is making 398whp at 16psi and if the rpm keep increasing, it should reach my goal 450whp at 16psi. Does anyone here having the same rpm cutout problem? Please help.
Thanks

Yeah the single turbo wasn't in the budget so I guess I may revamp my plans lol quite of few guys told me the same thing:/ but your build came out beautiful. 400whp &412ft is amazing numbers

Your running a AEM v2?
