hmmm, never really compared. i had a f23t and doug said it was 12psi wga, so we tuned for 12psi. turned out to be 15psi and my car would hit 28psi pretty easy. finally someone chimed in saying they had been tuning their car and set their wga to 9psi, so we lowered the wga down to 9psi and tuned for it... so much smoother.
however, reading through these pages, idk what i should do. yall are pushing me to k04 ha
