which would be better to get the ottp or zzp one? i am a 06 ss/sc. TVS with a 2.8 on gas. 50/50 meth with 12 GPH kit. full exhaust, air box mod etc....

so would you recommend the fuel return or the boost reference fuel pressure system?

i want the ottp as the regulator is located on top .

I seem to have same setup as you. TVS with a 2.8, full bolt ons, full exhaust, full cooling, 50/50 meth, 3 inch intake etc....

I bought the ZZP kit as at the time OTTP seemed to be hit or miss ( seem to have come back ) and I couldn't be happier.

Only issues with kit was it doesn't tell you the fittings option is needed. We had to do a few quick modifications to get everything set up, and the version they sell now, isn't the version that has the write up for the connection on the site. And it showed up with like 20 feet or some coiled line, no idea for what.

But with all that being said we still had it on the car working within half hour. And about 9 months later its still doing its job nicely.

does your kit use the evap as the return?

id have to ask my tuner, as I honestly don't know. I think so as that's what its connected to.

Ottp is nice bc you can read your fp and you get even distribution through your rail

The evap on the zzp kit uses the factory return
The option is running the steel brake line as a vacuum source instead of deleting your evap and using that

the full return is the best bet, zzp (i love them run their parts) doesnt have a true return style setup

the car stock has a return system its just different then a traditional system but ottp and zzp both use a rising rate regulator

zzp is based of stock ottp based off of traditional system

which one would you say is better?

I like the ottp setup better but there is nothing wrong with what zzp sales I think it comes down to which one works best for your wallet and if you really need it or not

yeah thats true. i went with the ottp one. i like the idea of having the regulator and gauge up front in the engine bay. once you factor in a fuel pump the prices are pretty similar with ottp's on sale right now
