Hey all, I was hoping some of you could give me a little help. I'm very up in the air right now whether I want to order the Boss 302 manifold and Tune from American Muscle. Was hoping anybody who has 1 could hopefully tell me
About the power gains and if it was worth it. Thanks!

What are your gears? Current mods? Please go with a different tuner compared to bama

Just got mine installed not to long ago and I love it. Minimal loss on the lowend torque and it starts hauling after 6000. Rev limiter was set to 8000 but I usually take it to 7500. Tuned by dasilva racing in toronto. 410/370 12.6 on 20" vossens and 275/35r20 trapping 116mph and 1.9 60ft. Need a better tire and smaller / lighter wheels

So many people talk about the torque loss, but to be honest, you dont miss it at all. If you want to be able to burn the rubber off your tires maybe, but I will trade the HP gains after 5500 any day. Feels like you put an afterburner on your engine compared to your stock intake. There has been so much banter online about torque loss and numbers in regards to the Boss IM, it has scared most people from doing the mod, yet most of the people that dis the install don't run it. The people who do run it like it.

American Muscle guys themselves told me that I could spend the money in much wiser areas if i was just daily driving. They said that if I am not track running it over 6500rpms really wont notice much at all. I decided I am going to do aluminum drive shaft instead and should see about same benefits but I have manual

Name someone who's had trouble. We want to speak with them and demand explanations of the circumstances. We want them in on this thread, no more here say.
