it varies A LOT depending your personal driving style, the tires actual diameter, weight and tread pattern.

 

expect 2-4 mpg loss. and some general rules:

 

people who are heavier on the throttle will see bigger losses.

 

people who drive more city than highway will see bigger losses

 

people who put on MTs instead of ATs will see bigger losses

My truck has the 5.3L with the 3.42 gears with 33" on 20s.. I was getting a combine city 70%/hwy 30% around 16 mpg. But now Im getting around 14 mpg. I dont have a tune just exhaust and intake. I plan on getting a black bear tune and 4.10 gears hopefully get my 2mpg back :lol:

i have 275 65 Buckshots on my truck and when i have the stock 265's on i could get 19 on the highway if i stayed close to 75. now i stay about 16.5 and thats not a 33 so tread dependant, id say you could loose as much as 4 if its a wide heavier tire.

03 5.3 Z71. Got 16 hwy. Bought Hypertech Economizer programmer. Check engine light sets code for knock sensor. Deprogram, light out. Hypertech technician says defective sensor. BS. Anyway, got 19 hwy. Put on 33 MT baja claws. Back to 16 hwy.

For grins, went to drag strip. Ran with it programmed and deprogrammed. 1/8 time is better with it deprogrammed.

Programmer now for SALE!!!

Hypertech sucks. Superchips is much better in the handheld tuner department.

I went from 18 to 14 when I got my tires on. I have lightened my foot up however and now I am anywhere b/t 15 and 16. I do about 50/50 highway/city.

Get somebody like Black Bear to tune it. There is a lot of information about live and handheld programming on the site. You'll find that the majority of people prefer these over handheld.

      I thought I was building a HD 3500 srw, maybe I was lost.

      Which 2027 engine will you choose?

      No doubt, I definitely agree with you. However, considering the 6.2 and 3.0 have been catastrophically failing with very little miles, I figured I would put trouble free. I’m at 18,4xx and still not a single issue.

      It’s never dry here but it gets hot. My 4 vehicles I keep at home drive an 18 mile loop. One 6 days a week. Two about 3 days each and one once a month. Only one goes on trips about 4 times a year 1000 to 2000 miles each time. One 26 years old gets driven once a month for 22 years. One 14 years old goes 6 days a week. The other two are recent at 2 and 4 years. All are performing normal no extra service other than that would be half of recommended or severe service in the maintenance manual. No extra water or steam out the exhaust or premature plug wear. I would consider an 18 mile loop would be enough. So apparently once a month at 18 miles for 22 years has kept the collector car running well. About 45 minutes a month.

      Transmission Temperature Hitting 220s

      By newdude · Posted

      It is working as designed.  NHT and non NHT trucks have the same exact transmission cooling setup.  NHT just gets a larger radiator.     The transmission cooler loop on these is as follows.     -Transmission out goes into an oil to water heat exchanger (item #1 in the first illustration below).  This exchanger has engine coolant opposite the transmission fluid and uses engine coolant to warm and then regulate the transmission fluid temperature when its in the operating window.   - From the cooler it goes to a thermal bypass valve (item #11 in the 2nd illustration below).  If the ATF has not reached the temp to open the bypass (194F), it loops back.   - When it reaches 194F, the thermostat opens and ATF then flows out to the oil to air auxiliary cooler (item #17 in the 2nd illustration) at the front of the truck.  From there it goes back to the transmission.     Your only fix would be to swap for the PPE thermal bypass delete block which will open the loop to the aux cooler all the time.  It will STILL run warm, probably 170-200F, but that's as low as you'll get it as its still flowing through the oil to water exchanger.

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.
