My stock turbo dyno


With mods in sig. Boost leaking IAT sensor.  I put down 299 hp and 475tq
Graph has a big dip in it at 3600 rpm. It's either a crack mani. No tune or something. I'll get with duster and pay him for dsp email tunes
Dyno was an awd mustang dyno at Cobb tuning in Plano tx.  I wanted to dyno in 3rd bc of the stock turbo. But I kept spinning. So he told me we will have to do 4th gear but stop at 110 mph I said ok but the lil turbo will spike some boost. It hit 28 psi.
I really need a tune I don't have time to tune it myself nor the software.  I have a bws on its way. I'm heading to the track again to see what it will do!
i dont wanna hear no crap, there is no tune just base line i got from  duster, and yes i had a boost leak couldnt do anything about it at the time....

475tq was probably from spinning/clutch slipping.

Nope no slipping clutch here. Don't hate on my tq spike. Lol
I spun 3rd gear not 4th!!!
And y in the hell u think I would make alot of tq with a slipping clutch?? Less the dyno spins over a period of time the tq/ hp it would show!!

How does a spinning clutch inflate torque numbers?

haha they dont LOL

Nice numbers, especially on the heartbreaker! Correlates well with your traps too
When you say its quot;untunedquot;, I understand its a baseline tune, but i'd have to say your a/fs look pretty good and unless you have a knock and timing issue, you seem to be pretty well tuned as it sits.. And i'm doubting the latter given you're running e85..

What are your fuel and boost settings in the dsp from 2-3k,3-4k, 4-5k?
I'm assuming the boost setting is about maxed with the 28psi spike haha?

well it just got cold here so i needed to add more fuel. i dont remember off the top my head like +3-5 %

how much boost in 3rd gear?

straight across the rpm range? i was asking to see if you have any major fuel changes between the dsp rpm brackets, so scratch that
Obviously where the dips occur, a/fs go a richen up some,  and boost drops off in those areas but i really don't have an explanation for you why now. Only thing i had was my above question as i noticed it very minimally at 3k and obviously around 4k

That clutch is doing a good job to hold that kind of torque.

normally at the track i hit 23 psi on my logs 22 in third and 23.5ish in 4th
