Default afr's getting rich as i leave the throttle

sup. i need some help on this one.

p28 ecu crome+ft 2.0 final multi 0.480 tip in set to 1.000
stock map
450 black tops.
semi tuned
tps is at 0.45

my afrs gets richer doesnt matter what gear I'm in, when I go to shift and let my foot off of the gas to push the clutch in, the a/f ratio dips down to the 10's - 11's (for a split second when driving and for about 1-2 secs when standing still) then it goes back up to normal .

Are you still using the stock O2 with the chipped Ecu? Or have you disabled it?

Hmm TPS? Check it with your multimeter, a haynes should give the spec.

You probably could! That's a much better idea.
I've only used uberdata, I haven't got to play with crome yet, Uberdata shows you this value as well though.
The ecu is programmed so that right after you lift your foot off the throttle it temporarily richens the mixture so that should you reapply the throttle there is no hiccups. I don't think that a chipped ecu disables this function, this could be your problem. As in it doesn't compensate for the injectors or something when it dumps that slight bit of fuel. How extreme is the change? Noticably boggy?

thanks for the replys everyone.
i fixed some things on my car to make sure they are not the ones causing the problam.
-i used to have inline resistors and now i changed them to a resistor box.
-my tb gasked had a very small hole for the iacv and now now i used a oem one.

but i'm still having these issues.
