Question about my tune
He'll this is my first post on the forum. I had a quick question on my tune I recently got my 06 350z fitted with a single turbo. It's basically a turbonetics kit but I went with a precision 6262 turbo and uprev for tuning. I got tuned at 7.5psi on my wastegate spring and my numbers where lower than expected and my dyno looks rough[img]webkit-fake-url://5ef45e94-6b9e-49c1-846c-e652786fbf21/imagejpeg[/img]This is my tune from them along with my AFR aswell. It seems off to me but wanted some opinions.Thanks for the help!

Check your link...
like anything in life, it's always good to get a second opinion...if there's another tuner in town go make an appointment...it may cost you money but a blown engine will cost more!!

This is my graph. I think im at 7psi, but who knows with my emusa wastegate. cutout is set at 8-9psi I think and it doesn't hit it. My timing is only at 6.5-11.5 at full boost, so that's probably your problem too. Last time I switched to higher timing I fouled the stock plugs and had to revert and go cooler, but I never tried it again

Okay the guy who tuned it for me said it was a conservative tune but I didn't know if he was just saying that cause he couldn't tune it properly that's good though. Does my AFR look okay? I don't understand why it drops off at 4K rpm and 5k rpm. Is that normal at all?

Looks like it's just be an error. You would notice if your AFR dropped to 10 since there would be a loss in power
If you can look at your timing map that might give you a better idea. 17-20 is what I'm going to be changing mine to at higher rpm's (aps tt timing map utec) if you want to take a look at it

I'd take it to another tuner still...it would worry me why I went from 11.5-ish and dipped down to 10 : 1 in those areas with no explanation...

Alright thanks for the input guys! Yeah I'm thinking about taking it somewhere else when it's all done. From what I've read online and compared to other dynos I should be making a lot more power that what i'm at.

That and I asked the guy to tune it for e85 but he said I wouldn't need e85 cause i'm only at 7 psi. I didn't know they couldn't tune it for e85 being that low. I have a 7.5pound waste gate spring in it so didn't know if he got confused on that or if I had some boost leaks.
