GI: Upstate Performance PEM's

is there any performance to be gained from installing these?

Probably. How much depends on your mods. They help reduce knock. Assuming your car has KR, there's potential for performance gains. If you're stock though, there are other things you should do first, but these wouldn't necessarily be far behind.

well i have a 3.4 pulley, hot air intake, colder plugs and thermostat, custom exhaust with no u-bend. the reason i'm asking is that i have exhaust leaks at both manifolds. i figured i would upgrade since i have to do the work anyway. i'm not sure how far i will go with the car, so i thought i'd spend as little as possible.

oh yes,

That was a set done asap needing install the next day. I didnt grind the weld 360* on the ID. I only did between 8-10 and 2-4 'oclock. Were its restrion to the stock port shape. but I normallly remove full 360 for visual apearence.

i'm still waiting for some kind of answer. if these will increase power then i'd like to get them. i need to fix the leak anyway.

I added the PEM, with other mods as the same time over winter a few years ago. A RT DP, 1.9 rockers, 3.20, and a early mild SC port I did. And went form a 13.7 @101 with a 3.4/DHP/upstate CAI to a 13.3 @105 as best with the new mod setup. I then got the big money TOGs at the time, and didn't gain as much as I was hoping for the money (12's). only got to a 13.1@106 after the TOGs over the PEM, and RT DP.
These PEM work great with a DP.
