No tune is scary! I will be the first to ask.... Is there anyway father Dodge could know this was installed if it was removed again, thus keeping the warranty intact?

As long as you put a dust cover back on your OE pulley then everything would be factory. No other changes would have been made anywhere else or in tuning to store any p1400 codes.

I am very interested in doing this! I live at 5,300 feet, and I have only ever seen 9.5lbs of boost. Would this pulley trick the car into thinking it was closer to sea-level basically? If someone snuck in my garage at night and installed the pulley, would I even really notice the extra power from 1psi? In the past every performance part I installed I convinced myself the car (pos Mustang GT) felt faster, but who knows if it really was.

I am excited to try this pulley, but don't want to be the first guy to do it either. Any other guys tried it yet?

LOLOLOL, if they'll de-warranty your ass over a diff brace, swapping a pulley will give them a 9mm brain hemorrhage. And they and the NSA have already logged your IP address for when you make your warranty claim.

More seriously, is there no where in any of the logs that an increase in boost pressure would be logged and noticeable? I'm not thinking codes, more if the motor blew and you were asking for warranty replacement and they start examining everything and every cache.

That's the beauty of this to me. I can possibly get a taste of how my car could perform stock at sea level, but up here at 5,300 feet. Not wanting to tempt fate by doing a real pulley yet, just need to see what 707hp ACTUALLY feels like since I have never driven my car anywhere but here. If it data logs slightly higher boost, it still will be shy of the factory rating of 11.6 psi.

Roger that.

 

[HighHorseman]

Never any hard guarantees when it comes to warranty and with what they're able to get access to, so that's always a gray area.

Damn.... me like. 50/50 is not bad. How close to maximum duty cycle is that pushing the stock injectors? I'm sure I'm just not thinking it through, but why would the pulley change result in maximum boost being pushed down the graph about 250 rpm? Or is that just an artifact of where the run was started?

Thanks for posting up.

On another front, any tips from the actual installation? Any problems, things to be aware of, short cuts?

How is the injector dc with this pulley. Last weekend da was -300 or less and better da coming for the next month to month and a half. So if da drops to -1500 would I have to stay home for fear of maxing the stock injectors? Asking for a friend. 😉

I vote you to be the 1st induct ee and we all pitch in to verify testing.

Just add a bap and get some headroom for the injectors

 

[hellno]

Besides it will just bleed boost if they max out , but I’d be curious about kr being in stock logs you already seeing it

Have an experienced Modern Hemi shop install any ODC pulley

I didn't check DA or water grains on that day, temp was 82° humidity 31%

I'll let the HighHorseman comment on the logs from those pulls
