Things to double check before dyno tuning
#1

I'm getting tuned this Monday. TMK, I've done everything I can to ensure a trouble free day at the dyno but I wanted to hear any words of advice of those "little" things to check that you may have had an issue with.
Basically I've gone over..
-Full fuel system (including new filter, pump and injectors)
-Turbo system (lapped flanges, new hoses where needed etc... no exhaust leaks AFAIK)
-Cooling system (bled cooling system)
-Clutch (new/used centerforce clutch)
-Boost control (staying simple with a manual boost controller)
-IC piping (checked for boost leaks up to 20PSI)
-MS1... all wires are tucked and checked for continuity
-COPS... installing these tonite. These are my biggest worry. I have an MS1, and not sure if I will need the resistor. I've also seen 2 diagrams where there is a second resistor/cap in the harness. Which one is right?)
-Oil (fresh Rotella T6 5w40)
And my last question... I have my stock 1.6 diff in the car right now. I have a 2 way Mahura sitting in my garage in a case all ready to be bolted in. Now I've read that dyno tuning can prematurely wear out a 2 way. Should I keep my 1.6 in there and wait until after tuning to put the new diff in or do it now?
-... Give me some words of advice

Looks like you hit most everything normal. The only other little detail I could recommend is to double check all vac lines. Clamps on every larger one, and a zip tie on the smaller ones. Just about every boosted car I've ever seen on a dyno has blown off at least one vac hose mid pull and it's those annoying little things that eat up tuning time.

I like to reference evans tuning checklist before going to dyno a car. Here is the link http://www.evans-tuning.com/pre_tuning_checklist.html. This mostly refers to Acura/Hondas but is some good info.
