Powermaxx turbo help!!!!!!

Hey guys the truck is 350 06 6.0 crew. I have a few questions about the powermaxx I just installed. Number one it doesn't whistle at idle like an 03 turbo even though I straight piped it with an mbrp 4 inch today why not? Number 2 it smokes when spooling it up black smoke until it lights off 2500 rpm why?

And also should I get a chip for it now due to the lag of the turbo? I will be honest I don't know if I like this turbo hopefully a tune will help this truck. I changed out turbos due to the fact that this turbo was dying and I am sick of the problematic stocker. Thanks.

Chris

does a powermax come with a VGT solenoid? if not yours that you swapped over may have been bad

why exactly did you replace your original turbo?

If you are still on the factory tuning, then yes. Get an x3 with tunes from gearhead, innovative diesel, quicktricks aotomotive.

The pmax on a stock tune is smokey and laggy. Any of these 3 vendors can write a good tune to get the thing to spool up like the stocker. Hope that helps.

I changed out the turbo due to the fact that it was throwing a cel due to an internal problem diagnosed by Ford. Now why doesn't it whistle at idle? It whistles like a bad *** when the throttle is pushed and also it spools up nice I hit 26 psi today.

I just installed one about a month ago with a batmowheel. I already had tunes so I got updated ones when I installed the powermax and I can say I really like it. I half sec of lag and she's off. I cant stop smiling when I punch it. Mine doesnt whistle at and idle either, but neither did my stocker. 1-4 lbs of boost is the sweet spot for whistling for mine.

Okay I just thought everything was supposed to whistle but I am going to call matt at gear head tomorrow and see if I can get the tunes by Thursday. Is the batmowheel worth it or no?

Cant say one way or another cause I installed it when I put the turbo in. I can say my 0-60 went from 5.3 to 4.5 sec w/the powermax and batmo. I can punch it at a 15mph roll and break traction too now which I coulnt before. I havent done a long wot run to see how much lower the egt are though yet.
