Back to Stock better MPG?

[Lazzman]

Since I recently discovered that my engine has the dreaded Timing tensioner issue and I will no longer be running it hard, so I am going to put it back to the stock configuration. It seems my hardcore fun is over with this X unless I am willing to invest the $1600 to fix it. 11yrs old, 175k mi- Nah.... Better to put it towards something new.

At the present time I am getting about 18mpg all around driving, with a 4wd sport, 4.10 gears and 5psd auto, 255/70/R16 tires. I love to blip the throttle at times and know it gives me poor gas milage, but it is an addiction

I will be selling the truck soon and want to make it last. The Volant intake, 73mm C&L, Custom X-cal tune and 70mm MAC TB will be coming off and the stock parts will be going back on.

I know with the stock air intake less air flow means less fuel and better MPG, though some say that performance parts will enhance MPG? I have not found this to be true for me.

Looking for opinions on whether I should put it back to stock or not for better MPG.

BTW the truck still runs very strong with no noises, leakes or other issues. The only reason I can tell it has the timing issue is when I first start it, I can hear the timing knock for a slight second before the oil rises. Also I found pieces of the timing Tensioner in the oil pan.

My issues with the timing chain tensioner or the V6 Sohc issue with it?

For a long time now I have had a problem with the vehicle bogging under acceleration, particularly in the 2500-3000rpm range. I also had a low idle and very strong shudder like misfire at idle. I could not figure out what it was.

A week or so back I replaced the lower oil pan because it was rusting out. In the bottom of the pan I found pieces of the timing chain tensioner- mystery solved.

If I keep running the engine hard with the performance parts and tune I am afraid it will make the timing chain tensioner totaly malfunction, costing me the engine which would have otherwise lasted many more miles.

Also in some aspects it seemed to run better before the performance upgrades- in terms of bogging and such.
