Has anybody done a tune with pcmforless and seen an improvement in gas mileage?

Also... if you have a tune from pcmforless... do you have any positive or negative feedback?

Thanks

 

I know that Darling Reject got a PCM4Less but since she didnt have her rear gears on the car yet it was giving her problems. I dont think she has changed the gears as of yet so I dont know if it helped her or not.

I have read alotta good things about them so far. My new biggest thing is if I would have problems passing emissions testing. I still have cats and AIR and stuff if that helps. And I live in Tucson, AZ but outside the city limits.
