2.8 Magnacharger pulley on a 6.0?
Has anyone put the 2.8 magnacharger pulley on the 6.0? I figure it really needs to be reprogrammed but was wondering if anyone has got away with this without retuning.

Had one on mine. It was good for 8 more hp and 20# torque vs the 3" pulley. I took it off. Boost comes in much quicker, but I thought there wasn't enough of a power increase to warrant spinning the radix that fast. I'll put it back on if I go to the track. If I remember right, tune was changed a little on the 6.0 with 2.8" pulley vs the 5.3L with the 3.0" pulley. Not much difference in total boost on the 6.0 with the pulley swap. The boost just comes in quicker

You'll need to have it programmed for sure. What year is your truck? If you have an 04' or newer you might have to up the injector size.

I went up to an 2. 85 from a 3.2 on my 05' 5.3 and gained about 25 rwhp and about 46 rwtq kept the same injectors and got a tune. boost does come in a lot earlier though. Still getting used to it as I did a trans, 3000 stall and a pulley change all at the same time so it just felt weird for a while.
