I have about 3100 miles on my oil change in my 2015 Silverado but it has been 10 months since I changed the oil and my OLM says 24%. Changing the oil this weekend.
I have a 2015 Silverado LT Z71 with MBRP single 3" exhaust, K&N cold air intake and Performance Tuning Specialists Stage 2 module. Just wondered if anyone had similar mods and actually put their truck on a Dyno, and if so, what kinda numbers should I expect?
