I have a GS400 also and can't spin 'em either...even when I have my stock 16's and I have a K & N intake, Borla exhaust and TM plugs)! I was never able to spin the rears and my car also feels sluggish off the line...almost like turbo lag but without the end result of a turbo kicking in. What GSteg said was interesting about the diff fluid. I still have my OEM diff in there (not for long) and I know the diff hasn't been changed for AT LEAST 4 years because that's about how long I've owned it; maybe the diff fluid could be the big culprit or part of it.
BTW, I already cleaned the TB, cleaned air filter, re-set ECU, replaced pugs, had a fuel injector service and later added fuel injector cleaner myself; I think I got everything. Still no dice. I'm the type of person that I want my car to be working in top performing shape BEFORE I add any performance mods so my stock baseline #'s will be higher and therefore get more power out of the future mods. Some members here might just be disappointed about the stock performance of their cars, not really look into it and wind up just throwing FI or other mods on. End result...car is definitely quicker but would have definitely been even quicker if the car was straightened out before hand. By adding mods, it will then be that much harder to assess where your problems might be coming from.

So, again, is it a good idea or not to flush high mileage transmissons (150k) and is there a difference between a flush and a fluid changs. This would be in addition to the diff fluid change. Is that a good idea either?

Never mind. I found it. It was originally posted by GSTeg. Thanks, man.
I let my friend borrow my camera, but the DIY change is even easier than a regular oil change. It's really easy. When you're under the car, take a look at the passenger side of the differential. There should be two star/hex bolt. I dont remember the exact combination, but there should be a lower and an upper bolt.
Tools Needed:
- (2) quarts of fluid, but you'll probably end up using 1.5 quarts
-Hex/star key. You'll need a somewhat big one so make sure yours fit before you start. I had to run out to my local autopart store to buy the key.
- Any type of pump where you can draw fluid and then inject the fluid. A siphon pump will not work (I tried, very messy result). Turkey Baster works perfectly fine!
- gloves
Basic Steps:
- Jack up the car
- Unbolt the lower bolt, which the differential fluid will drain down from
- Tighten the bolt back up
- Unbolt the upper bolt, which the differential fluid may be filled in.
- Take your pump and fill it up with differential fluid. Pump the fluid into the upper bolt.
- You'll know that you've put enough once the fluid starts to leak out of the upper bolt, and when it does, tighten the upper bolt.
- Lower the car
- Wash your hands
- Take a test drive
- Report back here
Warning: Gloves will come in handy. Differential fluid is probably the worse smelling fluid that goes into our car. Take a sniff and you'll know why .Having one of those orange hand cleaner will come in handy.
