Stock , 600 miles, pulled 319rwhp back to back twice, then removed ECM fuses for 5 minutes to reset LTFT`s (Long Term Fuel Trims), immediatley ran it again and picked up close to 8 rwhp. This is that last pull.

everything thing I have read concludes the real restriction is way before the mufflers and that an axle back adds nothing but sound

Here is my stock vs. tune dyno. As you can see in the south Florida heat and humidity my car pulled about 332rwhp/345FT# stock.
With the tune it looks to be about 345rwhp/357FT#. Considering the weather I'm happy, I'd like to get it back on the dyno once it cools down. I have just over 5,200 miles on the car. I was at the drag strip with 300 miles...what break in?

Now your 130 miles and hot motor would lower the numbers a tad |

Yes it is sad but true.
I also posted my 0-60 times around 6.8 seconds. I just came from the dealer and they where unable to do anything but open a case. The tech told me there was only one other case like mine and it was closed and marked as normal. He also told me that there where no PIs I think is what he called them. Which means they are not activally working on the issue that he could tell. Long story short While some are saying sit and wait GM will make good. I think everyone that has an underperforming L99 needs to get in and have a case open to put a fire under GM to resolve the issue. |
