Fuel Injector Replacement...OEM vs. Venom

Fuel Injector Replacement...OEM vs. Venom
My '95 Max SE has 110k on it and I've dropped two injectors (bad coils) over the last 4 months. The second one just dropped. When the first one dropped, I didn't have the $$$ to replace the whole set, so I'm going to replace the whole set.
OEM are about $750 for the set. Summit Racing has a set of Venom Injectors for about $550 - apparently they flow about 5% more than the OEM.
Has any one tried these in a Max? Any problems, other than slightly decreased fuel mileage?
Will the 'puter adjust the injector timing to account for the 5% higher fuel flow rate?
Thanks!

It's the injector itself...the inductive coil in the injector is an electrical open therefore the coil is shot...
Also a no on the 3rd Gens...There are injectors for 4th gens listed too...

The ECU may be able to handle 5% extra flow. You may be better off buying a used set of stock injectors. I'm sure they can be had for cheep, and you know the ECU can handle them.

I've had the injectors in for about a week now. They dropped right in...no problem with that.
They do seem to flow more, but I'll confirm on my next few tankfuls of gas.
Two other observations...
1. seems to idle a little lower
2. See to be turning lower rpms at high speeds. Before at 70 mph in 5th gear I was at 3k rpm...now I'm at 2.8k rpm at 70...
only thing i can figure is it's due to more fuel per stroke.
So far, i'm happy with the venom injectors. worst part is getting upper intake manifold off.
i haven't g-tech'd it, but it "feels" faster
