FIC or PTE injectors?

[TalonTSiGuy]

sup guys again.

well, im buying injectors within a week or so, and i was wondering if i should go with the FIC 650cc's or the PTE 680's??

Im guessing they probably flow at the same rate, but i was just wondering if you guys had experience with either of these injectors and your personal preference, unless they are both pretty much the same.


Thanks alot for your help

I am running the FIC 650's doing an excellent job.

Me too

Can't beat the price from extreme psi either.

I've had them both, they are almost identical bodies. Cant go wrong with either one, usually the PTE's can be found pretty cheap though. Got my PTE 880's for 300 shipped.

Sorry, kinda OT but what fuel pressure are you running and what are your current AFC settings? .... if you dont mind answering

I was running mine at 40 psi and they were dead on. Now I've switched to a blow thru maft and everything went straight to hell

Kinda off topic but why do the Denso 660's cost $100 more than FIC 650's? I'm about to get bigger injectors for my 50 Trim(selling my 580cc's) and wanted to know why they cost so much more? Thanks

What were your AFC settings? Mine are currently topping out at -28ish (most 25-27) with a hacked mas. Im just waiting for the AFPR to get in so I can put my mas back together. Im currently peaking out at 1600-1700hz on the AFC.

 

[98spydert]

I don't have an AFC. I have a keydiver chip to compensate and it was a little off. By turning the fuel pressure down to 40psi, it was perfect without fine tuning with a piggy back. The good old days before blow thru

rowlex & 98spydert:

What kind of HZ are you guys pulling?

 

[rowlex]

I dont know what the hertz were I wasn't logging that

 

[coltboostin]

I have 660 with a 2g mas. Im the low-20's to the high - teens. I have seen 1890 hz from my 14b, and 2380 from the 60 trim @23 psi

Do you have an AFPR? If so, what's it set at?

 

[coltboostin]

Yeah, I am running 40psi base pressure.

It is off a paxton off a supercharged mustang

So what are you set at now with blow through. I have been tinkering with mine and i have blowthrough also. I have mine set at 41psi right now, but if i go any lower, the car dies on me going full lean.

My fuel pressure is turned back to 43 and my MAFT settings are so jacked up. I ended up useing the 3.5" settings for my 3" MAF and I've got the AUX4 and Base 7 now. Whatever though, it got the car running right so I'm not gonna complain.

is that with line connected or disconnected? I tried turning it to the 3.5" too, but it went way too rich on me. I have my aux on 1 and my base on 3, which is for 610cc's.

That's with the vac disconnected. It's just at the stock base fp now. I have 650s but I'm chipped for them so I should be set up for a 3" MAF with the dip switches and aux4base2 with the knobs for 450s. In order to get it to run right, I'm set for 3.5" MAF and 500cc injectors. I don't know what to blame? The whole MAFT? The MAFT chip alone? The GM MAF? I don't know...
