has anyone put a wet efi kit on the new boonies? i was llokin aroun and found a cheap efi from a local performance shop and saw that zzp put a 70 shot on there 99 project car and was wonderin if i could run about a 50 shot!

Sure you can run a 50 shot or more if you do it right.
You will need to retard timing a few degrees and increase fuel to avoid kr.
A timing happy **** will lower the timing advance the fuel could be a little trickier.
You might be able to increase the fuel pressure before a run but it would be better to use a tuner to bump up the injectors.

what should i bump the fuel pressure up to?

Depends on your own data. You need a wideband O2 setup before you even think about that.

could i adjust it with the hp tuner though!

Yes, but not without WIDEBAND O2 data. Not just an AFR gauge on your stock O2, but wideband.

Wideband is the information you need, A tuner allows you to USE that data.
