Selling a used but good condition Sprint Booster. I was skeptical at first but tried it out based on recommendation of friend and it really *does* work. Install is 5 mins, 100% plug-n-play and reversible.
This is the newer version that has 2 different modes, each with different numerical settings. I found sport mode, number 3 was the sweet spot for everyday driving. Race mode was little twitchy for my tastes but I can see how it’d work great at the drag strip especially if you have xDrive.
Retails for $270+ shipped after taxes. My asking is $150 if PayPal as gift (else add 3%). Check my iTrader, DM me if you’re interested.
