I want to say thank you for the input for my prior post, narrowed down to which turbos I'll be going with and very excited to get them installed. My issue is fueling, I see many different routes for this. I plan on achieving 520-550whp on 91 pump gas and north of 600whp on e50 blend. I have a stage 2 lpfp, but that is it for fueling. Would this be doable with my current fuel setup, or would meth or PI be required? Car is FBO, will have upgraded inlets and outlets.

I was only able to achieve about 550whp on a stage 2 lpfp on E30 blend. anything more than that and my lpfp would tap out, and car would misfire. Im FBO with upgraded twins. I would definitely upgrade the lpfp if your looking for 600whp. But then you would probably need PI as well to reach 600whp, because the HPFP wouldnt be able to handle that amount of power.

Me personally with a conservative daily driver tune was only able to achieve 530-550 on a E30 blend, so i doubt you would be able to do it on 91.

I got to 566 whp on e50 mix. Attached you will see the dyno sheet. The fuel cut out on the top end of the run. If it wasn't for that, it would have been 580ish. I feel for 600+ , you'll need a stage 3 lpfp. If my meth kit was working that day then maybe we would have gotten to 600.
