WELCOME!!!! I have an E46 325i and like the BMW's a lot as well!!!

Just a 100' drag at a local circle track but gave me a chance to get on the car a little and see if it was all ok. Ran good so far but making more changes to the tune. Car is hooking good on 1st on unprepped track with 20lbs of pressure so I am pretty happy. Seeing 12lbs of boost too...

By adjusting when the fuel is injected time wise it can really help the idle out. You still need to adjust fueling like a carbed car by trying to get the most vacuum. With the A/F ratio sometimes stoich is not the best anyways with a larger cam. I still think many people don't pay attention to...

Glad it runs good!!!!

BUT...if you don't know someone that can tune or do it yourself it is not an advantage...

With the OEM efi and tuning you can -adjust fuel injector timing based on crankshaft rotation in degrees - helping idle with large cams -adjust fueling & timing based on engine coolant temp and air charge temp allowing better control of fuel at all operating temperatures

I just think too many people freak when they have an issue with a car that is 20yrs old and blame the EFI. Most of the cars have not had sensors replaced or some have vacuum leaks, etc. How well would a 20yr old carbed car run if never touched? I definitely like both, just in this example I...

That guy is on stangnet.com

Sounds like the pump to me. I have a fuel pressure gauge in my car and usually get fuel pressure in no time. If you only get 5-10 lbs something is wrong.

It sounds fuel related to me, you need to verify your fuel pressure, could very well be the pump. Is it loud when the car is running? It could be the pump relay too maybe. Many possible things.

Oddly with any fox I have had I never have had that high of voltage. Even my LX only hits maybe 13.6-13.7 with a 6G alternator. Weird.

Correct, if it is indeed a 96 motor it should have the GT40 heads.

It can yes, my fathers friend has a well tuned 347 NA that is 400+ hp and it drives great and is reliable. Carbs just don't adapt to weather changes like EFI does, that is probably the biggest advantage of EFI. I like the ability of tuning the injector timing for instance which smooths out the...

Looks awesome! What are you doing with all the stock EFI stuff and valve covers? PM me... It is definitely one of the cleanest looking bays I have seen in awhile:awesomework:

I am not a "carb hater" , I just don't see the sense in tossing out the EFI which is very capable for a carb when most of the time people do not do the carb setup RIGHT. They cheap out on the carb and everything else. A guy in town did the same thing with his 88 GT 10+ yrs ago and tossed some...

That is about as likely as one of my dreams coming true where I hook up with Megan Fox LOL.

Sounds like a bad fuel pump to me, check pressure like mentioned above!

What are you using the car for? Street? Strip? Both? A stock HO cam works fine with some 1.7 rockers or you can run a TFS Stage 1 with 1.6 rockers, B,E, or F303 with 1.6, Comp XE258 if you want more TQ, there are a ton of choices. TFS sells a spring kit that is around $150 that works well with...

Have you checked the fuel pressure and verified that it is correct? If you are lean at idle that bad you will not be getting good vacuum. Even with an E303 cam you should be able to at least idle at 1000 without a tune.

Welcome! What problems are you having? I personally would try and chase down the issues with the EFI and keep that due to the fuel mileage and better over all driveability.
