Hi all,

So I purchased tune support and new injectors (GM 36# fuel injectors, supposed to be 50% "bigger" according to the seller) for my 2008 HHR 2LT. Working with the seller is very tedious so I have come here looking for support.

With the preliminary tune I got from him, everything seemed to be fine (fine also with factory defaults). But each subsequent revision he sent lead to a rev hang at 1400rpm after about 15 minutes or so of driving (fine for the first 15 minutes).

The preliminary tune was based on logging without WOT. The subsequent revisions were based on logging with WOT. I have attached the corresponding files. Is there something fishy in the revision 1 tune? I am not sure whether the seller know what he's doing...

Thanks,
Pat
