First of all a little history on my truck: Early 04-I got it used with about 70k on it. Now has about 95k. I took it in for diagnosis as it was running poorly. They say the turbo needs rebuilt or replaced, about $1600 or so. One of the other items they found was the wrong coolant is in it. Apparently p.o. put the green stuff in. I added coolant earlier this year, but put the motorcraft premium gold in, not knowing there was the green coolant in system. Could it just be the wrong coolant got the turbo sticky and just needs cleaned? If it really does need replaced, what are good options at similar prices? I'm not interested in making more power necessarily, but would welcome greater reliability.
You don't HAVE TO get a custom tune, but it will help. The PowerMax is quite a bit larger than the stock, so you have more lag without tuning.
I never looked at the specs on it, so I wasn't sure about that. I just know that it was a direct bolt on. But then again, mine is a direct bolt on and I had to have custom tuning otherwise there would have been a big "dead spot" with it.
I ran with no tune with my PowerMax for a while and it was fine. There was a dead spot around 45mph when the TC is locked, but that's still there with the tune, just not as bad. The PowerMax is 63.7mm and Eric at Innovative told me the stock turbo is 58mm, he said it's more of a race turbo than a towing turbo. It has very good driveability for being a larger VGT turbo.
So how does it perform while towing...or can Eric correct that with a tune. I would love a power max, but I tow often and dont want to sacrifice andy workability of my truck.
Not meaning to hijack but what are the advantages of the Powermax supposed to be over the stock turbo? What about disadvantages (other then the "dead spot" we've already heard about?)
