14.5 is the lean limit. i leaned my car out to about 13. for gas mileage, but it goes a little leaner down at idle because of the big intake. adjust your pressure regulator.

man beejay if i get a fox, i will need some advice

 

[wikedcobra312]

stang 8u what are your mods, nice numbers btw

 

[beejay31000]

everything i know i learned on the site, but i would be happy to help

 

[stang8u]

its runnin 16 15 14 up till 4600 or so real leen then after that it balances its self out 13 to 12

 

[stang8u]

i thought i would at least break 300hp with a race cam at least i got 300 foot pounds thats what counts

 

[beejay31000]

thats still a lot of power for a fox. do you have an adjustable fuel pressure regulator?

 

[stang8u]

of corse

 

[stang8u]

its set at 50 psi

 

[beejay31000]

put it at 35

I guess I will be the first to say it. When you do get a chip and have it fully tuned and get your A/F where it should be you will more then likely lose HP and Torq. But be safe on the other hand.

After I installed my blower and took it down to have it tuned I was sitting at 13.8 A/F which is very lean for a blower car. After teh tune was set-up and my new A/F was 12.1 I lost 34HP and 28Torq.

Lean makes more HP and Torq but also not safe.

 

[stang8u]

it actualy needs to be higher than 50 psi the car is still to lean i eather need to chip it or go down to 24# pound injectors then i can run 35 psi

 

[beejay31000]

dropping the fuel pressure prior to the regulator would increase the pressure at the injectors.

safer is mo better in the end

mo better
