SR S13 SR20DE Won't Rev Past ~3500 RPM

First post to Zilvia, although I've used the forum itself a lot, but anyways...

I have a late model S13 SR20DE, that's right, DE, and it's bone stock besides the Wiring Specialties harness that I got for it. The motor is in a '86 200SX S12. I have an issue with the motor sounding like it's bouncing off rev limiter at roughly 3500 RPM, and at first, I thought it was a MAF issue, but after switching through 3 different MAF's, I'm starting to doubt that's the problem. I thought then maybe it was my TPS, I had a brand new OE one in the box, so I slapped it one there, adjusted it to correct voltage, and still the same issue. With it being a 'V6' SR ECU, I'm really not sure if these flash codes or not like the DET's do. There's not a crazy amount of info on the motors for me to dig into.

So, any input from you guys???
