How do you like the sound of the FM 70? My spacer has a whistle sound in the upper RPMS just before shifting when your on it hard. Feels like your truck lost about 1000 LBS. Gotta love it, glad to hear your happy. Now I just gotta figure out how to get the $$$ To get Mikes tune, dont know how my Hypertech compares.
Awesome i think the 70 sounds like i got just a little more rumble, awesome at a idle and not obnoxious at all then give a little more sound on the top end , but the might be the the in take or spacer not sure, i haven't drove a lot yet to here it , but its well worth the money, i was worried that it would be to raspy but its very conservative. and yes get the 5star sct from mike rad~~~
