importwarrior how do u like it ???

mine is a trilogy from the first Group Buy.

it works just as good as the aeromotive I used on another car.

once set it holds fine. I have it set to 42PSi and running 650 - 1050 injectors.

no issues at all.

If running aftermarket bigger injectors, can this be of any benefit?

 

Yes, aftermarket injectors don't have the spray pattern the stockers do, it gives you the ability to help that some. Delivered fuel volume does increase with increased fuel pressure but its not linear, meaning doubling your fuel pressure doesn't double the delivered volume.

another question then.... is bigger injectors better? Has anyone gone with trilogy's biggest 220 lb injectors? What does the experienced tuners suggest and/or use themselves? I need to buy 2 injectors and was just thinking why not go bigger to support mods I hope to do later or does it not work that way?

Stock size injectors will go a long way with a maf-t or safc to tune your air/fuel ratios. I would definitely not jump to a size like that.. maybe a small step up from stock but you need to be able to "tune" your fuel then.. and you'll need a wideband to do that.
