safest way is a standalone or piggyback that is capable of adjusting the fueling curve through the rev range, personally i wouldn't entertain a P&P to run anything more than a CT9 as that's what they were intended for, that's not to say they wont run a TD04 without issues but that's just my opinion bud. im sure tons of people will disagree now though but as said in previous post if you gonna run a TD04 on a P&P ALWAYS have it checked leave nothing to chance
