• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

do i got valve float?



Graph your MAF flow if it's valve float your airflow will stall (go flat) up top. Use the log function in Torque pro. You may need to regap lower it may also be blowing out your spark.

new coils, made no difference.
did some scans, lt fuel trim is -4 at wot, no knock while wot,
misfires at wot at 6000'sh rpms, will throw a code but only when going to first to second, wont throw a code 2nd to 3rd.
sometime the code is misfire for cylinder 6 sometimes cylinder 4.. its random....
another weird thing it was a hot day yesterday, did a wot run threw 2nd, but it wouldn't shift to 3rd at all till i let off the throttle.......here is a video

then driving home tonight I tried again, and it shuddered and misfired for a second and shifted into 3rd..... tried it a few times and it shifted into 3rd every time.... only difference was it was much cooler outside(roughly 10 Celsius cooler)

I wouldn't do anything valvetrain wise without upgrading springs in these cars.

Get LS6 or L76.

They're cheap enough not to care.

You also have no need to be shifting at 6500~...I honestly wouldn't run it past 6k. You're not making much power there anyways.
 


Ya I want to, been so busy though I got a 2nd son coming into the world June 30th and my wife is going nutters lol.
