Im going to put on all these mods:

Performer 5.0 U&L
E303 cam
70mm TB
1.7 RR
76mm MAF
if i forgot any all my mods are in my signature


i want to know if im going to run lean or not?

i also wanted to know if a AFPR a must as soon as i put on these parts?

 

you will prolly need a afpr i did after my cam swap

 

so nobody else knows?

 

i decided to get a AFPR so what pressure should i put it at with all my mods in my signature

 

i was think 40 to 42 but i dont know

how do you know what to set it at?

 

40 is good starting point, but with or with out vac i dont know i have does it both ways and with vac the 40lbs is good and with out 40 lbs is a litle hesitant, the preesure drops 1 around 10lbs with vac. I swear i have read set it with out vac more than once like i said i dont know. try both like i did and see wich works better for me 40 lbs with vac was good.

 

i have an AFPR and a guage coming now
