dont think so. someone has put S&S headers on a older W body though, firewall needed some love...

[19Cutlass94]

Has anybody tested fitment on a W?

I've gone past that, but not for an extended period. mine were usually in the 16's with lean cruse enabled.

there was a guy on quad 4 forum that leaned out the engine fuel on is Q4 and could literally do twice the mileage with a single tank. but i think is cylinder heat was very high.

yes it would be. lean AFRs do have high cylinder temps...

it's why i am kind of wary about leaning it out above 16.2:1... it's what i run for highway fuel mode... i think any leaner, and it would start misfiring or knocking...

Agreed, I have not noticed any difference in my Mileage with the EGR removed. I did notice when I took my headers off that my mileage sucks. A well designed header should increase fuel economy, which is a plus if your car is a street strip car.

I turn the EGR off and no mpg loss to stock. If you are adding egr, then possibly, but that goes against my goals of efficiency.
