Yeah, I know Brian's site. But I'll bet that article was from before the Suby ECU was cracked and EcuTek came state-side. Like Kevin said, why use a piggy-back when you can have the stock ECU do it, as well as so much more! That's the reason why I ditched my UniChip for a reflash. |
No, the parallel fuel rail mod is a really good idea when you approach max duty cycle. Aftermarket fuel rails already incorporate it, but if you decide to skip fuel rails, I would definitely consider doing this. All UTEC users should do it too.
