After having a rough idle on cold mornings I tried Archoil AR9100 additive package in the oil and it helped but did not cure the problem. Replaced injectors with a set of the stock Warren's with upgraded spool valves. These injectors make the truck run smoother with engine oil temperature at 38 degrees than it did before fully warmed up. I previously worked at a light duty truck shop and I've replaced hundreds of 6.0 injectors. This is the smoothest I've ever heard a 6.0 run!

No more cold starts, smoke and poor performance. I installed the stock Warren's with upgraded spool valves and my truck runs like new again. The new injectors cured a number of problems. I wish I would have done this a long time ago. I've had them in for 6 days and have pulled my 43ft toyhauler 400 miles with no issues. Communication with KT just needs to get a little better. Happy Customer.
