Easy tune injectors for 500hp

Need recommendations for best injectors that are easy to tune. Struggling with fic 1650cc heard these were the worst injectors to tune

Goal is 500hp im there just injectors are holding me back

What kind of fuel are you using?

In general, as you increase injector size, you require the injector to run at shorter and shorter pulsewidths in the idle and light throttle range. This area can be challenging for an injector (think about filling up a glass of water using your sink faucet, vs filling up a glass of water using a fire hose... which can you do easily and consistently over and over?).

Our 1650cc injector is quite a large injector and is also an older design than the newer high impedance injectors which does make it a more challenging injector to tune, but with the right setup it should work out well (EMS, wiring/grounds, tuner, etc.).

If you're looking to make 500 whp and no more using E85, you could probably get by using our 1250cc low-z injectors but they wont leave you with much headroom. You can move to our 1450cc low-z injectors to make things more comfortable which might be the best compromise.

Moving to a newer technology high impedance injector will give you an advantage as far as ease of tuning in general, so in that world you have the option of running our 1100cc high-z if you run at a higher base fuel pressure (roughly 55-60 psi base would be required for 500 whp on E85). We also have a brand new 1650cc high impedance injector which rocks, and would be a good fit and should be easy to tune.

To switch to a high impedance injector, all you need is to bypass your factory resistor box either with some wiring you can do or with our bypass plug which is $22 and makes for a plug and play swap.

**If you are using gasoline you can go with a smaller injector, so let me know and I can make some other recommendations for you**

Hope that helps give you some more info, if you have any questions please feel free to give us a call at (561) 427-0082.

The new FIC 1650cc High Z injectors are amazing.

From the FIC website:
WHP on Gas at 43.5psi 90%DC Turbo 752.86
WHP on E85 at 43.5psi 90%DC Turbo 579.12

So if you are on E85 those look to be the perfect size, and If you are on gas then smaller would be in order, maybe the 1100cc.

My car on 1100cc made right about 450whp on e85 with the BFP maxed out.
