I've been working with Joseph for a couple of years now. We went from Stage 1 (stock truck), to Stage 2 (upgraded intercooler), to Stage 2 E85, to finally Garrett PowerMax turbos with the supported mods!
I remote STREET tuned this truck, off the dyno. He put it on the dyno today(on E85) and the results were ridiculously consistent:
Pull 1 - 629whp 547wtq
Pull 2 - 631whp 549wtq
Pull 3 - 631whp 552wtq
Torque is 'Bookshelf' flat, and very very safe.
These bigger turbo trucks are REALY REALLY becoming something that is gaining popularity. And the results are there every time!
