First post exhaust question / new member

Thanks. What color am I looking for on the plugs when running properly? When lean?

Without lead it is hard to read a plug, Grab a magnify glass and flashlight, you will be looking for white hot spots and sharp erosion at the plug tip if you are running lean
 
Pulled my back plug today to check them after the V & H exhaust install, high flow ac, and Dobec TFI. Does this look like it may be running lean?ImageUploadedByTapatalk1361978623.419247.jpg
 
Stock gas mileage was 46 mpg and 32 with my TFI so I'm too rich. Chris at Dobec helped me adjust my TFI and I think mileage will improve now. Technical support and GREAT CUSTOMER SERVICE from Chris at Dobec!! I'm so glad I went with this product!! Thanks to all on the forum for helping to steer me in the right direction with Dobec!!! SERIOUSLY....the best decision I made thanks to y'all!!
