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
