The resistor mod I'm talking about Is so you can run high indipendense resistors. Is this the one you dont really think works ? I'm confused. ??

The resistor mod on the injector ballast, it's just disconnecting the ballast, crimping 5 wires together at one end and then sticking a 6.3mm male spade connector on the other end, then plugging this into the connector. This will allow you to use high impedance injectors.
Not heard of a resistor mod for the CTS, although that does sound like a terrible idea!

As you weren't specific when you said the "resistor mod" i had to guess at which one you meant. The most common one on cars without an injector resistor pack is the one i described.

The resistor mod for the CTS : https://www.ebay.co.uk/itm/15bhp-Pow...e/302879407430 Big box, small components, enormous mark-up! Little, if any gains in the real world!

I thought the mod being discussed here about injectors just allows higher flow injectors to work better ?? By that I mean standard flow 940 injectors fail to get enough fuel in when you increase air flow boost etc. Perhaps I'm wrong as I'm no expert

So are you saying it's not the way to go to do the mod and run me7 s ? ? |

It's really only worth running the higher flow injectors if you do all the other mods. Bigger Maf etc. No point in just putting higher flow injectors and doing nothing else. But yes that is the right mod to run higher flow injectors

http://www.injectorcleaning.co.uk/flow.htm I picked those as the first i came to as being the right flow rate, also i used a slightly different table to the one above, the one i used is from the G40 Owners Club so is based on the injectors that will fit the VW G40 so will also fit the 940 as well : https://www.polog40.co.uk/article_injector_table.php These are already refurbished saving you about £70-80 on having a secondhand set refurbished : https://www.ebay.co.uk/itm/Ford-Sier...s/133363173469 Like Mark says though, you only want to do that once you've done all the other mods so it actually needs the extra fuel.

I do plan on using my 16t and a 3 inch maf aswell as a bigger intercooler and bigger exhaust. So you think the cassie injectors will be better to run that the me7 ?

FYI
Unless you have a very high power 940 you won't need more than 350cc injectors. In point of fact, the standard injectors for the turbo redblocks run at 300cc/min and that's good for 185bhp at the flywheel (at 100% maximum duty cycle and 3 bar fuel pressure) - not ideal as there is no room for hp increase at a later date. 350cc/min injectors run at the ideal 80% max duty cycle, and 3 bar fuel press are good for 215 bhp, and at 100% = 270 horse. So, basically, over 350cc is just a waste of time, money and effort unless you're making, plan to make over 270 bhp; and you'll create problems that didn't exist to boot! BTW, Green injectors run at 465cc/min @ 3.8 bar fuel pressure (over 3.5 is not ideal as it puts undue strain on the standard type fuelling system in general) and are good for 285 horse at the 80% max duty cycle - with up to 355 at 100%
