I had a FRI Sidewinder cam installation done by Modern Muscle of Oswego, IL a few months ago. Justin and crew worked diligently from 7am until 9pm to get the cam installed and base tuned it on their Dynojet. As a result, I was able to get the installation performed and have a drivable vehicle in just one Saturday. We ran into a few snags, but these guys never balked at finishing the job and a friend (co-worker?) of theirs showed up towards the end to lend a hand. I would whole-heartedly recommend them as a good shop for installations in the Midwest area. FYI: their dyno may be a bit stingy, but the work was great and we did probably 20 pulls to get the correct items dialed in to the tune.
