motordyne M370 mainfold installed and dyno tested

They tried looking to see if they could tweak anything but theres nothing else can they can change. Yeah the a/f looks crazy but its fine, it's just not averaged to give you that flat line we're used to seeing, no clue why they didn't.

i would e-mail uprev and have them send you a tune, they have done this with me in the past...or go to another tuner...the AF ratio should "try" to be as consistent as possible all through redline, thats just way to erratic. and it shouldnt in the 14af at WOT, you need new targets for the car to hit

I appreciate the concern, the afr is fine, it's erratic because its not averaged, and it's in the 13's at wot. the shop that tuned my car has been tuning Z's for years with UpRev.

Well then they should know with these cars 13:1 air fuel ratio is not the magic number on these motors as I've seen time after time with multiple tuned VHRs. They like the extra fuel, most power that was made for me was 12.4 - 12.5. I made 16whp+ over baseline on a 85 degree day with 60% humidity with a good amount of heatsoak.

Do you think the new M370 mainfold is making the car run leaner? I see the avg AF at 14 and min at 13.2. 13.2 AF should be perfect for NA car at WOT.

there was a weird dip in the afr around 6300 after installing, they fixed that after but it made no gains

How many pre and post dyno runs did you do today?

Id like to see tonys opinion on this, but I'm wondering if you would see gains if you had the stock intake installed. I could have sworn I read an article where a 350 saw gains switch when it swapped back to stock intakes while running MD's art pipes and exhaust. Granted, I don't recall what kind of intake it was running, maybe it was just a bad design on that car.

Thanks for the dyno sheets, numbers, and the super fast install/dyno time.
