The tune shouldnt make all that much of a difference as its just the pre canned 91 tune like every other tune. The air filter im thinking about changing to one of my extra K&N cones from previous set ups.

As for gases, i can smell nasty exhaust smell because i am running no cat so its hard to tell whats weird and what isnt without a wideband.

Gas used is same as before, but with smaller tires and UDP in it evens it out.

I will be working on it tomorrow night and messing around. I will update as i go

50k on platinum plugs is fine for everyday driving, but you should change them up pronto for max performance ... true story >>>>>>>>>>>

When I had about 25k on my 07 wagon the tach needle started flickering a little at idle - when I first got the car it was rock solid.

A Ford tech I know said that if was really bothering me I should replace the plugs and it would go away - I did and it did ... apparently as the plugs started "going away" the deteriorating spark can sometimes interfere with the operation of the tach.

Just because the plugs are nominally rated for a set distance it doesn't mean they remain good for that distance - the ECU can compensate for some really bad plugs in terms of the driving experience - even as performance and mileage go to the s***s.

Same btw for the stock plug wires ... if you're not running something like Magnecor you should change them when you change the plugs.
