Their dyno sheets show the HP and torque for each year and motor.

OBD 1 was used up to 1995. not able flash the ecm for performance. OBD 2 came in 1996 The system controls alot more of the vehicles fuctions and can be reflashed with performance tuning. OBD 2 vehicles normally polulte less and get better milage.

 

thanks for the links chopper.

 

I think what muddy blue mean was get a 96 or newer because you can get a hypertech or superchips programmer for it. If you get an older one your options are somewhat limited because you have to get chips or an aftermarked pcm. OBD I and OBD II are the stlyes of diagnostic ports on these trucks.

 

thanks for the charts

 

ok i see

 

yea thats what i meant. i re-read my post and it didnt really make sense- sorry.

 

that ok i'm not that good at mechanical work any you would think i am owning a ford

 

which ever engine you do decide to go with.. try to find one with a 5 speed.. these trannys last alot longer then the autos and will be less of a headache in the future.. also i would probally go with the 5.2.. you get pretty good gas mileage with only 20 or so less horsepower then the 5.9... but i still which i had a 5.9 just so i can say i had one[:@]

 

wow, according to those graphs, I would rather run the 87 octane program on my 2001 5.2 ... the difference between the gain in both are:

Premium - +21 HP + 31 TQ
Regular - +18 HP +35 TQ

I would be missing out on 3 HP but gaining 4 lbs/tq ... I Like torque =D

Oh yeah I'm liking the top speed increase also... 128 MPH ... hehe
