I currently have gen2 2.3l whipple with only a 2.75 upper only. The car has dynoed 572 with 16-17degrees which i know is really conservative. question is im getting ready to put a 4r70w in and ide like to be at 600+ to the tires with E85 through the auto and im thinking of just putting a 2lb lower on and calling it a day, or should i go to a 4lb lower and a 3.0 upper? which is going to be the best combination for my car? nothing is done to my heads and im running stock manifolds not going to put headers on cause with the auto they are just too much of a pain in the ass so please dont tell me to put longtubes on. any info will help

I'd go 4lb all day long. A lot easier to change your upper to get where you want to be boost wise.
what PSI should i be around with the 3.0 upper and 4lb lower?
