FWIW M&M said that he was running meth and that the kit was custom modified for more power....he also said he had some belt slippage too. Here's what he said:
"Ok I'm not gonna' mislead anyone, we have made our own changes to the kit. So it's not like it shipped & these chanegs we made have nothing to do with ESS. We did whatever we did on our own. It's probably around 625hp equivalent. Have meth as well.
The octane is around 98RON, so I think thats 93 or 94 in the US equivalent. Stock tyres. We having some issues with belt slippage on the setup we running so the belt basically slips after each gearchange & feels & sounds like the clutch riding but it's actually the belts slipping."
