HELP Steer me away from a Chevy LSx

The 1UZFE EGR Delete Kit is available for sale here.
I've made 540rwhp (uncorrected 3500f) 580sea level corrected whp at 13psi on a 100% stock long block, at the time I hadn't even changed head gaskets (just put cometic's in to be safe)

Just fyi

Stevieg,

Up until now Justen's was the most powerful per psi stock longblock I was aware of. Your numbers are off the chart :eek:
Do you have the details and pics posted somewhere. Would very much like to see this beast. I am guessing carefully crafted manifolding, great tuning and a LARGE turbo...

But yeah, really good tune 11.8-12.1afr and lots of aggressive timing map. There is a corrected dyno chart floating around showing 573whp/600ftlbs using j1349 (523hp/550ftlbs uncorrected), I've since moved to a different dyno that back-to-back runs shows about 30hp less, since then I've switched to a .81ar turbine housing and trimmed the timing/afr's some more and it's back up to 540whp/560ftlbs uncorrected. This new dyno reads about the same as a mustang dyno (ie low)
