I need to get busy getting my car tuned in.

Spooler · 09-13-2024, 04:49 PM

This is what one thing I need to learn how to do. When I get time. Life has me busy.

Spooler · 09-19-2024, 12:20 PM

So much to learn.

Enjoy, The man behind Xonarotor turbos.

Still had it. It is the most frustrating thing ever. I never had this issue with Vince's tune. Vince tuned my car twice and it was perfect. That's what I expect and the dang guy freaking delivered.

Spooler, Did you ever get your stumble at 2800 rolling into throttle fixed? I have a 2017 370Z with Fast Intentions Stage 2 with UpRev dyno tune and have what sounds like the same issue you outlined in your post. Thanks for any insight you can share.

I had a couple of problems, but it is hard to say exactly what was causing it. I had a coil pack issue under load at 16psi of boost. I put a brand new set of Nissan coilpacks in the car.

Thanks for that info... did the new coil packs solve your issue? I have thought I may have a coil issue as well but don't know if there is a way to test them without a trip to the dealership.

Yes, that fixed it. If they are old, just replace them and the spark plugs.

Spooler · 09-29-2024, 07:48 PM

I had fun at Z Nationals. First time I have had fun with the car in a while. I did the dyno thing. Car made 900whp/713tq on 23psi of boost. It did really well. I left early, I was warn out and had to work today. Somebody said I won it. I have no idea. I would have stayed a little longer if I would have known. Nothing worse than trying to give out something and the person was not there. I feel bad for that if that was the case.

I have learned a ton over the last 3 years. Sometimes you just have to fail to get you to that point where you figure things out. So, failing is not a bad thing. It is just part of the process of learning.

The look on my face after every dyno pull before I flip the switch to the next level. Just like Bobby Bushay right before he passes the football. Yeap, that was the smile on my face. LOL

Meanwhile, there's someone somewhere reading through all the details in this thread like this guy is explaining it to them.
