just wondering if anyone else has put a helix throttle body spacer kit on a hemi. I did and it was off and in a box 2 days later where it still sits today. anyone else get bad results from a helix spacer? my truck would get bogged down between 2000-3000 rpm or so and had an intense vibration and drone sound.

 

Never heard of that happening....... Usually a chip would correct that problem.... one way to also do it to is to re-install it and after you do that, take the "-" terminal off the battery for 10mins, this resets the ECU and it should makup for lost power..... otherwise if you don't want to do that, just sell it....

 

i always reset the comp with any mod. did it with the helix. same result. i cn say when i would get on it it sounded great, but just taking off normal i hated it.im really trying to stay away from chiping or reprograming.
