You will pick up HP if your running big tunning. On a stock truck you wont see crap IMHO.
The pumps from kennedy and TTS are the same pumps......just differences in electronics, mounting, and price.
Or you can peice together your own kit with other pumps. Many other choices......
In answer to your question though.......If you have to prime your truck to start it you dont need lift pumps. Lift pumps will just be a bandaid to a problem you have. IMO investigate the actual problem and fix it.
