I dynoed today and got about 400 and 800 at 20 percent load mind u stock imput had to be concevitve blah at 30 psi I've hit 50+ on the street so I'd say at least 500 hp I'm ok with that mods are in sig

Moparman is at ~4000' altitude I think.   That makes a big difference.

He is around ~2400' at home, but can easy get above 4,000. 

Got ya,  I checked at mccall and it was 38xx.   

 

regardless the altitude has a big effect on smoke vs fuel at 0 psi.      I THINK the ecm does something around the 2000' altitude area in the maps.    I always  noticed a big change in north platte - grand island area in terms of smoke reduction that is abrupt.

Ill look when I'm around my tuning computer. 

The maps aren't in udc pro similar to alot of the tables for a vp truck,   I seem some stuff in Winols when I load the ecm bin file, but it is hard to know and I didnt ever care enough to dig deeper.

I'm at 1 to 2 k feet

I'm going to say around 80% is your starting point. 

Thanks, I'm at 86 now with 75hp so I was guessing 80 for 150hp I'll have to see what it does on my current tune and go from there. 

BTW when are you planning on doing 7x10, I know you've been mentioning it latly. Are going with vco and about 320 pop? That's what I asked dap for, should have them in few days.

@Mopar1973Man 90 percent

I'm guessing because of 14mm housing and being automatic you can start higher. But then like you said earlier you want more on take off.

Yea altitude is key. I have same size injectors as @Mopar1973Man and still stock HX and pretty sure I’m starting above 100%

Yep I want that turbo to spool

My 7 x 0.0085 injectors smoke pretty good at 90% at 2,000 feet elevation. My performance tune starts at 90% and my daily starts at 80%.

Hmm turn ur duration down I run almost minimum

I've been kinda following your foot steps on turbo and now injectors, I just got a set coming of 7x10 vco at 320 pop. Hopefully my hybrid 62/67/12 won't run too hot. I know I can tune it out and maybe won't need wiretap at all as I hardly ever used it before. Where do you start your canbus at, I know you got auto but just curious. 

Will someone please explain why the 320 pop instead of a higher pop off number, like per say for example 400 on the injectors. If I remember the lower the PSI pop the worse atomization is and it doesn't burn the fuel efficiently. which leads to poor performance and mileage. So if I am guessing the higher the numbers in bar the more advanced the timing is??

Thanks!
