Stuttering top of 2nd gear

[Rather B Blown]

Since i put in the Overkill pcm about 3 weeks ago, my car kind of stutters right before 2-3 shift only from 5.5-6k rpm (yellow area) pulls fine up until that point. Also 1st gear pulls fine until 6000 and shifts fine there, problem is only with 2nd. Before the pcm, the car obv shifted at 5.5k so i don't know if the problem would have happened before pcm install or not. Any ideas?

SES light?

no nothing at all...i dont know what it is. But will is a member of a local board and said he would reflash the pcm for free, so hopefully that will fix it.

Are you running a stock pulley?

Mine did that, when it was cutting off fuel (injector disable) ..before the shift. I had to change the values.

yeah it does feel like its leaning out and slightly misfiring at the same time. Hopefully the reflash im going to get Will to do will fix it

if its tuned for a 3.4 u should have done pulley and PCM at same time... i would put pulley on before i go reflashing things.

get a scan of it happening and look at injector PW, if its 0 .. your injectors are cutting off (which is bad) .. and you should see some KR too.
