1550 miles from Spokane to Las Cruces. Let me just say that I was a little overweight (25,200lbs)gcvw. I weighed before leaving town but what could I do? I know, please no flames. Anyway, Dual 4" exhaust from Northwest Custom was great. Sounds great looks great. Comp box with wire tapped kept me at 65 even up decent grades. Yes I could go faster but with my weight I wanted to keep it slower. Towing I had set on 3x5 and I never saw egts above 1185F. Is this normal? Seems low to me but thats what the SPA read. I dont have injectors though. The BD remote exhaust brake saved my bacon. I made the mistake of going through Box Canyon in CO and I would be in the canyon somewhere right now without that brake. The shifter mounted remote switch was nice. Mileage through the hills and with winds avg 10. 2 mpg and most of the somewhat straight aways avg'd 12. 6, this was manually figured by gallons used by the way. Not bad for the weight I'd say. Sorry such a rough report but I'm tired and wanted to post a little something. EGT's right? wrong? please let me know.
