I'd leave it stock for reliability. That's what these were built for and that's what they are. I had an '84 with the Banks Sidewinder kit and it was running fine when I sold it with nearly 200k on it. But,that was back before they decided to sell diesel for more than gas. It didn't feel a whole ot more powerful than n/a. I guess adding some power is ok,but don't try for a whole bunch. Also,why lose fuel economy? That's why I run them. My '91 Suburban with 4.10s and 4L80E could roll down the hiway at 75 mph all day and get 20-22 mpg with 35" tires. I feel the power is adequate with the 6.2. It moves along just fine.
