So, shop diagnosed problem I was having with various CEL lights after going over severe road bumps like rail road tracks as battery ground cable that goes from battery to starter as shorted. Apparently, the previous shop did a poor job of installing long tube headers. They didn't move cable so the heat from the LT melted the battery cable insulation. Secondly, they didn't clock the connection at the starter so when the insulation melted the exposed cable was too close to the metal heat shield of the starter so a severe bump would cause the heat shield to shake and cause the exposed cable to short. The recommendation of the new shop after consultation with the GM dealership was to replace the 3 vehicle computers and of course replace the ground wire. After the repair I now have a weird problem. After the vehicle sits for a prolonged time (over night or after a 9 hour work shift) when I turn the key I get a reduced engine power message, a service stabillitrak CEL, the gas pedal is not responsive, and if I put transmission in gear the truck will only idle around. If I wait 30 secs or sometimes as long a couple of minutes the truck will fire up with no warning messages or CEL. A check with a primitive hand held scanner reveals 2 codes related to the long tube headers. Does anyone have any idea of a fix? The only difference since the new shop touched the truck is new computers, new battery cable, and new tune. I think one shop uses EFI live to tune and the other use HP tuners. Wonder if the malfunction is a possible theft deterrent function of my original key and the new computer or a "no hack' gremlin left behind in the tune from original shop. Thanks in advance of your reply.

thank you for the feedback. Got a quote for $7670 (4097 for lift, 1547 for tires, 1260 for labor, 129 for alignment) which seems steep. Guess I got to go or no go.

Looking to do the BDS 4 in lift with fox coil overs. Does anyone know what the backspacing is for the factory 20 in wheel? Wondering if 35's will fit kit.

Heated/cooled Seat Conversion
theduke replied to rich22's topic in 1999-2013 Silverado & Sierra 1500
anyone know status of the "tech wiki" instructions to add cooled seat option to sierra slt that didn't have them? BTW, I received this feedback email from amerigon http://amerigon.com/ccs_seating.php which intalls a system called:CCS Thanks for the inquiry. We can do this. There are 2 options. 1st - is the replacement of the current factory leather with our leather. This would include the necessary perforation and required special foam to allow the airflow. Retail cost for this package would be $2,499. 2nd - is to use your existing covers. This requires a more lengthy process. We must disassemble the current covers, then send the parts to another location for the perforation process. Most customers have elected to do this only on the front seats due to cost. $1,299. This would take up to 10 working days. We would try to reduce this, but must plan for extra time. Much of this is to accommodate shipping time. Either way, the results are terrific. The cooled seat function is very nice. One additional point, your current seat heater switches become dormant. The CCS system uses a different and much more effective heating process. Our Atlanta facility can handle this effort My preference is to not have dormant switches...
