Hi,

I currently have the Edelbrock 599 kit installed in my 2011 GS with the dry sump. I m looking to upgrade to a flex fuel kit to add some extra ponies. My GS has the 52# injectors and the higher capacity fuel pump installed. In this configuration, I am currently making 505Hp/490Tq. I also wish to add the 3.25 pulley I purchased some time ago.

Do you think that I can just use the existing fuel pump, upgrade to 60# injectors, swap pulley, buy the DSX kit and a retune?

Thanks

60lb injectors won't be enough. Get 850s or 1000s. 850s will be a stretch at 650rwhp.

Fuel pump also won't be big enough and will need to add a pump.

Thanks for the recommendations.

I ran 80# injectors with a BAP with e85 making 675rwhp. Was on this setup for about 15k miles.
