Need tuning advice on 19 A10 Procharger P1X Stage2

[Gregory347]

Car is all stock with 600 miles. Running the Procharger tune it picked up 150 wheel horsepower. Max boost was 10lbs with a 4.5 inch pulley. The computer was pulling 4 degrees of timing due to knock at 6000 rpm with 93 octane in the tank. Procharger claims the tune is fine, they will not remove timing and want to send me a 4.62 inch pulley to lower boost to hopefully stop the knock retard. What is the best approach to correct this, lower boost or remove some timing?

Have PBD tune it. Done.

Add some boostane to determine if it's false knock.

Will do

Add some boostane to determine if it's false knock.

I agree will all of the above. Add boostane and get a PBD tune!
Are you on 93?
E85 is the key if it is available.
What rpm is it shifting at? It should be making more boost than 10lbs with a 4.50 pulley.
I made closer to 17# with a 4.38 using a D1x.

What blower is it? But yes custom tune is in order.

Edited my title to include blower as being a P1X. Full tank of 93 octane. Just picked the car up yesterday. The shop that installed the kit put in on dyno to check the Procharger tune. When he noticed knock he emailed Procharger to pull some timing out of the tune. The Procharger tuner told him to turn off the load cell on the Mustang Dyno and run it again instead of adjusting the tune. So I got involved and was told boost was too high and they would send me a 4.62 pulley to lower boost instead of adjusting the tune. According to the shop these are not the correct answers. If they cannot fix the tune I want them to refund the money I paid for it. Shop is capable of fixing/retuning the car but its just principle now that Procharger was paid for a tune that needs tweaking and seems that they do not want to do it. Another issue I have is that Procharger advertises certain power gains with their tune and I am not seeing anywhere near those numbers with a 150 wheel horsepower gain.

I don’t think a 4.50 will be more than 14psi on that car

 

[Gregory347]

4.50 pulley is supposed to be 8.5psi. Procharger tech support told me they ship all kits like mine with 4.50 pulley and never see more than 8.5lbs boost. The air quality the day the car was on dyno is probably why car saw 10psi.

Again I have a D1x but a 4.88 on mine made closer to 12# of boost.
I have never used the procharger tune but an after market tune from PBD is the way to go.

Idk if a stage 2 P1X will only see 8.5 psi with a 4.50 pulley. Being a realist I don’t see how one of those 2 tuners is better than the other. But hey, swing away swingers.

 

[Gregory347]

I bought the kit and their tune with confidence based on information I read here. Most of what convinced me that Procharger was the way to go were posts by @ProChargerTECH. Maybe he could be of some help?

My 2018GT with Stage II P1X sees right at 9 psi with the supplied 4.75" pulley

My kit shipped with a 4.50" pulley which Procharger tech support verified to be the correct pulley. They offered to send a 4.62" pulley to lower boost. Now I wonder do I need a 4.75" pulley.

 

[Chris Barnes]

I wonder that as well. It seems that Procharger shipped these 18/19 Stage II kits with a few different pulley sizes which is odd. I just verified again, mine is stamped 4.75". I can tell you for sure that I already see positive knock on our crap AZ 91 octane with only this moderate boost pressure.
