I start here. Here is all the recorded info since I've owned this truck. I try to document everything I do to it by the date and mileage.
Gotta bear with me, but here it is page by page!
Bought it 11/16/10 with 115,608miles
Anal? A note: Total mileage is as per the odometer reading. Actual miles traveled per tank are adjusted 10%. My GPS gives me an actual mph that is 10% faster than my speedometer reads due to tire size. It worked out simply that when the speedometer reads 60mph, the gps reads 66mph, 50=55, 40=44 and so on. It may be off +/- a %, but that's what I get regularly. My friend the sheriff has confirmed my guestimate. I do have an ultragauge, but have not gone through the bs of correcting it!
Anyhow, I will update as I go. I did replace my K&N with a freshly cleaned and oiled one. I will also clean my TB and MAF in the next few weeks, but it will be documented of course.
I hope I can get some practical info to you guys. I would like to see a real life gain with the snorkel. My plan was more for mileage improvement than being able to submerge my Toy. BTW, what does everyone do with the clutch driven fan when going under? I've seen them eat radiators before. My old Blazer had dual electrics on a switch for water crossing.
