so i was messing with my wideband it runs really lean at 4,000. my safcII was at +2 at wot on 4,000 and still running at 15:1 to 15:6!!! i had to turn it WAY up just to get to low 13's! keep in mind its stock port, stock injectors, n/a with an exhaust and cone filter, and thats it!

It sounds like you have problems with the secondary injectors kicking in. It could be sticky injectors, grounding problems, etc. Check out stuff on the 3800 rpm hesitation.

it WAS a little slugish before i turned it up but now i cant even tell when the secondaries kick in. im glad i ran into this problem before i put my turbo in what can i do since ill be using 720's to better ensure the saftey of the motor and my wallet.
