Well, after a few towing runs, I'm not terribly impressed with the egt changes. I was hoping for at least a 100 deg change with the 16 housing and an additional 50 with the BHAF, but I'm thinking I'm getting around 50 total. I was looking at HTT's website and they have HX-40/35 hybrid compressor and wheels for 200 bones. Anybody tried this? I know, I know I'm cheap and on a budget with the truck, but I wanna live fer today and have a little fun with it. Having to baby the go pedal up the hills just isn't fun enough.
