Okay, I am cruising on the highway, and when i gun it in 5th around 2500 rpms i get great acceleration for passing, but as it rounds up to 3100rpm i feel power drop and car starts feeling sluggish... never happened before until i reseted my car (battery unplug).

I had done the oscai right before the reset and it felt great and more powerful, but after my power just sucked *****.

max 2000 se 5speed

 

Install some F-22 raptor afterburners. You won't lose any power after that. GUARENTEED!

 

Shift to 4th, that should cure your problem.

 

See, before i didn't have to shift. Now do you understand?

 

Let me guess, You must have an intake !

 

Its most likely a bad MAF...
Thats what my problem was...

 

My guess is you didn't reset you comp fully. Did you leave the Neg. post off for a good 24 hrs. after you installed your intake? You check to see if your VIAS is hooked up? Look to see if you have two little vacum lines hooked up to a box just right of your intake runners if you're looking towards your engine. Peace_
