I am just wondering if getting a dyno tune done to my vehicle would be worth it. I dont have a supercharger or turbocharger and my current mods include:
K&N CAI
JET TBS
Troyer Underdrive Pulley
Troyer E-fan
Gibson Headers and Exhaust
I already have a custom tune that I got from someone online and the power is good but I am only getting around 13 mpg highway and 10ish in town. just wondering if getting a dyno done would increace my mpg and maybe even give me a little more power? And does anyone know how much a dyno normally cost? I am also looking at getting the weapon x ignition coils, would this be a good mod for power and mpg?

 

lose tbs, quick?-who did online tune?-phil

 

also mileage and maintenence done on vehicle since new?

 

Agree 100% with ditching the TBS. It's doing nothing for you at all. I honestly can't see changing the coils giving you any benefit either. The plug either sparks or it doesn't. If it DOES spark, the fuel ignites if the mixture is correct. This whole concept of a "hotter" spark (or whatever Weapon X might call it) is just advertising hype in my opinion. Motorcraft coils and plugs were designed for this truck, and I'd stay with them.

Unless you drive with a VERY heavy foot, I think your gas mileage is too low and I'd suspect your tune is not right. If whoever does your dyno tune knows what he's doing, I feel sure your mileage and performance could be improved.

A guy named Mike Wilson from Fleet Tuning gave me a custom tune for my predator tuner. Who is Phil? Also, what do you mean by "also mileage and maintenence done on vehicle since new?" The mpg i got before all the mods was 16 to 17 mpg and with all the mods and tonneau cover i put on i figured i should get better mpg, not worse. I'm all up to date on maintenence with tire and oil change, vehicle only has 17,000 miles. I cant get rid of TBS because I had to shorten up my CAI to make it fit.

 

What harm does a TBS do?

 

only good on carbed or tb injected engine-put stock tune back in and see what mileage does-that may be your problem

 

Is the stock tune ok to run considering my mods? I know they recomend you get a custom tune when you put mods on.

 

you will be fine , this way if mileage is the same-you can eliminate tune as being the problem...
