when it comes to dyno graphs - how come on some power runs, the afr starts off around 14-15 and drops to safe levels around 3500 revs (max boost)whereas some eg mine stays a constant 12:1 throughout the whole rev range. do u think theres a difference in fuel ecconomy between them

Was your graph after you got the S-AFC tuned?

yep it was initially tuned to make 270 then i got the hiflow done and put in back on the dyno and it made 305 without changing the mixtures however the midrange power is fucked - what u think?

Ideally the better controlled the AFR's are, the better the car should be. Your one is probably smoothed out more because they should've done that with the piggyback.

hiflow = loose in the bottom, gain in the top.
