What did you do to your NNBS GMT900 Tahoe/Yukon Today?

3 out of 8 coils seem to have issues upon tearing into the truck. #2, #3 and #6 are the problem children. #2 is not firing at all, #3 has weak spark but operates normal upon 2,000 or < RPM's and #6 wants to heat up to 210 degrees while all other coils is 73 degrees. Needles to say I will be replacing all 8 coils if I don't just trade the damn thing in to the dealer

Which coils does yours have? Melco-Mitsubishi?

Finishing up the wrap on the dash of the Silverado. I need to see if I can adjust the gaps but it looks pretty good.

It was wet here today. I drove the 07 a bit hard. Its pretty interesting how even with traction control and stabilitrack, if you leave your foot in it when its wet you can still get it to spin into second gear. I will check the catch can and post pics of my findings tomorrow!

I don't think I've had mine past 90mph. The L9H is plenty ready to go much faster, but I am at the mercy of my tire speed ratings.
