Pic's are before and after torsion bar crank.

 

With the new rims and tires 285/60/18 toyo a/t I lost 30-40 miles to the full tank of gas, and thats keeping my foot out of it.

 

Questions:

1. If I go back to 265 I know I will get some of those mpg back but will they look to small with my current setup and adding a zone 1.5" body lift on top of it?

 

2. I know you can lose mpg with lift and aerodynamics, but if I do add the 1.5" bl and stick with a 285 tire will I see more mpg loss? Will the zone 1.5" bl cause me to lose additional mpg? I know its not a monster lift compared to others but I'm sure some of you have been in the same boat.

 

thanks,

God Bless

Also this pic is current and months after I did the torsion bar crank, it seems to have added the rake in front again, is this bad shocks? I know the front is the heavier end of the truck, the bump stops were clearing after crank, but they are slightly touching now.

 

 

The shocks are originals with over 115 thousand miles, which I know is well over due, but if I do replace the shocks will it pick up the front again or will I have to crank again after new shocks to get level?

 

Thanks,

God Bless

Any input is much appreciated

Well, your torsion bars are "tired" somewhat. Your shocks have little to do with front end sag. Also,. you say you lost mileage with the 285's, but did you re-program for the 285s? If not, then your mileage isn't reporting correctly. If you did.... obviously the 265's would help gain that mileage back due to the weight difference. And I don't believe the 265's will look small. They'll be fine. :)

ah stevens: yes I got the tire specs and put it into a flahpaq superchips, although I have recently tried to use it and I get a "vehicle did not respond correctly", so I'am unsure if it saved the information/settings or not, (although i did do it before I started getting an error reading).

 

I am looking at falken wild country 265 at $150 each, but the 285's at $159 each are tempting.

 

Do I have to re crank after adding bl and new shocks, since you say the shocks will not help it any?

I lost 2 mpg with my 3"lift, but I have since got it back through tuning. I had the nose dip and I did the 3" and didnt touch the torsion bars. It still has the nose dive obviously but its not noticeable with the bl on. I say keep the 285s. I wish I had gone 305s now

gregs: yea I'm just looking at the 1.5" for a little more clearance, I'm not crying about mpg and trying to do mods at the same time, i just dont want to lose what I already am getting, 18-19 highway, since I do long commutes. But after college Iguess it wont matter since my commutes will be significantly less and in town.

 

I always thought you had to level the truck when doing a BL?

 

And no thanks with the 305's.lol, Yes it is true once you start adding you keep on going bigger, but I know my limits. Although I do have to say, those trucks look sexy.

The body lift does just that,... it lifts the body. You won't have to re-adjust the torsion bars. It sounds to me the superchips program didn't take. Your mileage might not be as off as you think. Does it have the ability to upload software updates from the superchips website? If so, I'd look into that and see if you can get the truck programmed right.

What he said. U can't go off anything till CPU is tuned for taller tires.

I will check into it tonight/tomorrow. I know I set it for tow and then tried to reset it back to 87octane and thats when I started getting the errors, so as of now I do not know if it is on no settings (stock) or still on the tow setting, but I did re calibrate the tires before it started reading errors.

 

I have never plugged it into cpu/website since I have gotten it, but it also has never given me a "vehicle did not respond correctly" reading. For x-mas I will be getting a blackbear tune, and do away with the superchips flashpaq.

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      By Chuck FB · Posted

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.
