AHC Fluid Change with 35's

[bozncsurf]

Just an FYI

First off, I followed the awesome ahc fluid change instructions - they were spot on.

Second, if you have 35's or 33's with an aggressive offset (aka wide stance outside or flush with the fenders) then be careful when bleeding the front globes as the front end drops significantly lower than it does in "L" mode - in which my tires contacted the fender. Pay attention as the front end drops fast because of the engine weight.

I luckily escaped without damage but I did ruin a good pair of underwear!

If you are doubting your technical ability for this job - STOP! It's easier than pumping gas (and less painful to the wallet).

I'm really grateful for this site.

I didnt think you could run 35's with just the AHC

You can, 2 ways to accomplish lift - Slee override switch and/or "Hoser" lift, search ahc lift under FAQ by Hoser (he runs 35's as well), Sonk76 has an awesome setup with AHC plus aftermarket for his 35's

Everyone is pretty much anti-35's here .. The only change I ever noticed was that braking required a greater distance, as far as acceleraton - its as slow as its ever been. Eats gas like a Ferrari but doesnt perform like one.

My 33's burn enough fuel as is, i dont want to imagine even worse performance and mileage than i already have.

Block the EGR and disconnect the WAI - it will give you some extra power and better mileage ...

What is the offset you have with 33'?

How do I go about doing that^?? What is the WAI? Im not sure what my offset is, Ive had these 285 75 16 terra graps on forever

Look for "EGR delete" - YouTube
WAI - warm air intake

EGR -
Burned gas from outlet manifold go back to the intake manifold, contaminate the system while reducing the amount of oxygen ...
By blocking the EGR you will have more oxygen in lower temp and therefore more power

WAI heat the air coming from intercooler just before the cold air meet the EGR
Taking out the heater will allow better flow of air and again lower temp..

Actually you can also take out the catalytic unit and again have better flow of gases which will reduce resistance, pressure and temp

Let's put things in perspective - the change is not big but if your 33' or 35' run you slower in 8% then deleting EGR will bring you back to base line
I have seen changes of minus 100 - 300 rpm at given speeds
