I've had personal experience with "PEMs" on my car, and many other cars of friends and acquaintences who I've worked with, given advice to, helped tune, etc. and one thing rings true of all these cases, the cars ran slow, as slow as a car on stock manifolds.
It's a fairly simple matter really, the front manifold itself is the same size as the head port. Enlarging the first 3/4" of each runner does nothing for the main size of the runner, nor does it address the most restrictive part.
In addition, the rear header is also larger than the head port, and the welds create MAYBE 50 thousandths of protrusion in the flow path, and still does not get smaller than the head outlet.
The ONLY real restriction that is helped is the protrusion of the #6 primary, which overall is a very VERY small restriction.
Stock manifolds, especially the front one are turds, and everyone knows:
you cannot polish a turd.
If you port your own manis, go for it! Free mods are great, but I don't understand the people who pay hundreds of dollars for a little grinding and a few welds, that have never proven a dyno gain.
All "gains" from PEMs are sort of like Alky, "I killed X knock, and added X boost, and it feels lots faster.....prove it.
Save money for real mods. I've been there, and really wish I had never fucked with PEMS and just saved my time and money for headers in the first place.
