i run all blends of biodiesel in my semi modded truck. no problems and i run custom tunes on my SCT (Econ, Street, Hybrid Race). i have been thinking lately and wondering if running biodiesel would effect cylinder pressure? biodiesel has higher cetane and with the increased timing of a high power tune may cause extra pressure. i don't know, just thinking out loud, hopefully someone with more insight can help us out.
