Thread: Plog vs PEM or Ported TB vs HVTB

I can't ever get much of a straight reply regarding the HV3 and a ported TB. I don't intend to race my GP but to use it as my daily driver and more or less maintain the same speed. Plus, what I have read says the HV3 and ported TB only return gains at higher RPMs. Since I only have CAI now, and will be adding a Plog and new downpipe over the next few months, I want to know if it's really worth shelling out the money for that right now. My Impala is my performance car, so I don't need the speed out of the GP.

The HV3 is going to show the most improvement in higher RPMs. So, to really support that, you will want some good mods along with it. HVTB, Plog, 2.5" DP, and intake. Then, a PCM so that you can actually rev to the RPMs where it makes the most difference.

If I remember right, it added like 10 peak WHP, but at like 6k RPM it added 30WHP. I think the L36 usually peaks around 5200 RPM, so you would want the higher RPMs to make use of what else it's giving you. Pair all of that with some ER rockers and that thing would haul some ass that might make you wonder where the whine is.
