It's only good for that much in the right kind of driving. Plus, people like smooth engines, which means heavy flywheels. Plus, it's harder to stall a stick with a heavy flywheel, and most people don't drive stick very well.

I do a lot of P&G and when I do drive steady it's usualy at 45 - 50 mph.
Would be interested if there is room for improvement.

I'm not sure how light those come. With an auto tranny, it won't make as much of a difference, however, as most of the weight is in the torque converter. Keep in mind, being a long-ish stroke I6, the 4.0 has a lot of internal rotating mass, and probably doesn't have a super-heavy flywheel anyway.

No but I did a 3rz stock was 28 lbs I went with a Fidenza 11lbs.
It was a lot easier to stall. But I gained about 4 mpg. With no real driving change. To me it made the truck faster smoothed out power and when driven easy gave better mpg. But offroad u has to use 4 lo. It would stall to easy at low speed. And took practice at pulling out.

Was in my 98 4x4 Tacoma manual hubs 5 speed

That's what my truck has and why I was wondering. I considered it when I was doing my clutch this summer but didn't have the spare $250-300 or time to wait for the 11 lb fidanza I wanted. one of those clutch slipping in all gears and towing 5k lbs next week situations. It takes FOREVER to rev with no load and I can take my time shifting and still hit the next gear before the revs drop that far.

Any updates?
Anyone else have any info on the subject?

Your avg from 6 tanks before vs 6 after first post shows only a 1 mpg improvement, well within normal fluctuation.
