Sal/anyone,
Forgive me, but is the 25-35hp & 25-30ftlbs with or without a tune? Can we expect a little more from a header tune?

You do gain a little more from tuning.

Sometimes you need tuning to get those figures.

All depends on how good your engines are in the first place.

Cam timing is critical.

Some say that cam timing should be spot on, but who knows

Some say that it's been heavily researched and tested in Finland and it clearly makes a BIG difference.

Some say it's a black art that supposedly a candidate for a DIY write-up.

I'll be damned. Sorry, Raikku, I haven't been paying attention. Carry on.

Hey Sal, What kind of performance improvements from the headers do you think I'll see with ESS vt550? I got carried away and installed th FI after I ordered the headers. I wasn't sure if I was going to install them when they arrive until I did some research, but with my name on them my decision is made.

Thanks to member dookateh setting up a group dyno run at EQ Tuning in the San Francisco area my beast will have a before and after for the header install. I may also be able to take decibel readings. Headers look awsome! can't wait just to open the box.

Thanks

Not sure about how much power on a supercharged car.
I guess you will be the first one to find out.
