Hrmm...that is strange...but it defintely sounds like a tune or ECM relearn issue. Hopefully it will get better, as there is no way the car should have lost power.

But my other thought is this...Is a LT header + solo HFC option really that much better than shorties + HFC? I'm really not sure....the LTs may flow a tad better, but you've already removed the stock cats before so that should have gotten you better results than just doing shorties alone.

I don't want to be a debbie downer...but my guess is you may gain a little power, but not too much over the shorty + solo HFC option.

Definitely datalog it and then have Vince look at it though, as there could be something going on there.
