this math is based on the findings of Amanda’s 98 gs. The only mod is a very cheap but yet effective HAI to delete the crappy stock 98 airbox setup. The car still has the ubend and crappy side inlet muffler setup and stock t stat and plugs and fuel filter.
She has had a stock tune in her car and she would avg 23.9 mpg Last time she was here we did a little tweaking of the maf and timing tables. She came back this time for an interview (which she got the job), and avg was 25.5. we spent the weekend using her car instead of mine and tweaking the timing and maf some more to dial it in closer to 0 and change the fan settings.
she went back hme and said the dic said she got over 30mpg. now she may have had a tail wind none the less we will work with the #s we have
avg miles per yr is 15k then you take the old mpg and using 17 gallons a refill and getting the same mileage across the board that equals roughly 37 full refills of gas per yr
now you take the avg for 30 mpg and it is roughly 30 tanks of gas
using very loose numbers here you take the difference at $2.75 a gallon x 7 tanks which is about 120 gallons. using that math you would be ahead $330 and save the environment from 120 gallon worth of emissions
now assuming you got the same 30 mpg for a second year netting the same 330 dollar savings you would have the cost of a hptuners pro setup worth saved in gas alone. now mind you this is a stockish car.
I am sure you are saying the learning curve is too steep and I dont have the time. You drive the car dont you. with pro you get standalone capability and wideband input.
Now wide band for the sake of ease is 200 bucks now you have a tuner a wideband and the internet. if you can research and have the guts to try tuning you can dial your car in nicely.
Another point to ponder the HPT setup comes with 8 credits you can use or aka 4 vehicles, if you and another local were to split the cost and split the tuner time you could even make this who proposition cheaper still or trade tuner time for parts and or services like I did.
so for those of you that say I wont be helped by a tune or I am stock what do I need a tune for, may I direct u to the above example.
The other I forgot to mention is that you could set one tune up for mpg then yet another for power. now the last but not least thing by far, GET OVER PULLEY ENVY. congrats you are running a 3.4 with 12* of timing while I am on a stock pulley and maxing out the timing and robbing less hp from the motor to spin it and reducing the heat produced also. I will say right now that I bet a 3.4 on a reduced timing or stock timing tune would run at least a .1 slower then a similar modded 3.8 car with max timing tune.
I will continue posting about amanda's car and what happens when it is no longer stock which will mean a u bend delete and a newer style TB and muffler to reduce the restriction factory put in place along with a smoothed front manifold.
