ok I reset the ecu after the post about the possdible performance gain and went for a drive and was dissapointed
- I dont feel the booste I used to at around 4300 rpm
- It shifts a tad bit lower
- it is slower on the o-60
- feels more sluggishg overall

the only good thing I can say is that it idles lower after startup

any ideas and why this happens and any ideas on how to fix it or start to work it back

The ECU is a learning ECU. You have to give it a little bit of time. That is my only guess.

I think you are supposed to do that after making an adjustment/mod, such as installing a CAI or advancing the timing. This will allow the ECU to reoptimize itself.

it takes about 1 or 2 weeks for your computer to learn again, break in the engine, etc. mine was horrible last week too, but it's getting a lot better this week.

I disconnected both the negative and the positive for like 2 hours.
