Hello, new to the forums and hoping I'm doing this right.
A few years ago I purchased a beautiful 02 K2500 Suburban with the 8.1l and allison tranny combo; its the best truck I have ever had. I now have 115K miles on it and unfortunately up until now have not had the money to do much to it except oil changes. I'm now ready to do some maintenance; due to the high dealer costs will need to do this myself. So I'm hoping for tips/guidelines and am posting since I read through the whole Silverado forum and didn't find anything.
1. What do I need to do to tune up/maintain the 8.1?
2. I'm planning on switching out the stock instake with a CAI; changing the MAS to a Granantelli and adding a Airraid TBS. Any suggestions on any of this?
3. I'm also going to swap out the stock plugs with E3 Diamondfires; and Granantelli spark wires. Any issues here? Do the coil packs need to be replaced too? I haven't dug around the back side of the engine too much; but is there a dist. cap/rotor that I need to replace?
4. And yes, I'll be replacing the O2 sensor as well as the pvc filter. What else do I need to do?
I appreciate any real world 8.1 experience in tuning and help with this somewhat different engine config than I'm used to.
