after non squential mod im running lean

on my PFC the knock readings are higher then before. should i just delete the settings i had before and use the base maps untill i get this beast on the dyno in 2-3 weeks?

also how do i richin up the fuel on the PFC? does lower numbers mean richer?

i know the PFC knock readings sucks. but it is higher then what i have before. at 50% throttle it will jump to like 27. before at WOT it will be at 30. also at high rpm the car will cut out. what the mechanic said is on the verge of denation.

also im assuming both turbos kick in at the same time then i should compensate for the extra fuel needed shouldnt i?

again does the lower numbers when tuning in the PFC mean more fuel?

In the fuel maps a higher number is more fuel or find the PIM screen and up the % for the rpm range needed, this is a quick fix. You need to write a rich map to start with. HIGHER numbers are richer

if you are running non seq then u dont spool to 10 psi as fast as a seq system, if this is true you can non run any leaner then you are with seq, if anythign it shoudl be the other way around

because i was comparing the base maps to goodfellaFD3s is maps and i found that in the INJ, IGL,and IGT the numbers are always lower if not the same. if higher numbers mean more fuel then i guess the base maps on the PFC are really rich.

the base maps are tuned ofr intake, DP, HFC, CB and IC
as compared to goodfellaFD3s's intake, DP, MP, CB, IC and a streetport.

so do u guys think i can run the PFC base maps and be pretty safe with the mods i have untill dyno time?
