    Ok so I realized I need to get my car running right. Couple close losses made me realize if I had just a little more power I could compete with some pretty decent cars around here. My old dyno sheet had 299/338
    Tuner recommended 30# injectors and a 80mm Pro-M meter.
    Added an SCT 4 bank chip and tuned at 252/ and something like 290 tq and smells like its running rich (even though he said it was right) Ironically I was pulling out of a gravel parking lot and ripped off my passenger side wheel well and discovered a huge vacuum leak. Plugged the leak and seems like it's running even more rich now.
    Buddy said he has some 24#s I can try.
    Here's the info:
    DSS block with forged pistons (PI style, stock compression)
    Fox Lake Stage 2 PI heads
    PI intake
    70mm TB
    Stage 1 custom cams
    80mm Pro-M maf
    MAC shorty header
    Full exhaust

    Specs for heads and cams

    Do you think the 30s are too big?

    No I would leave the injectors in. You've got quite a bit of n/a power your tuner was right on using them. Running rich sounds like maybe a timing issue to me. Too much of it. Do you have a handheld you can adjust it with? Or do you have to go back to your tuner? Either way don't mess with the injectors they're fine. Your issue lies elsewhere. I'd start with timing and go from there

    I agree, I think the 30's are fine. You have an underlying tuning issue it sounds like. Do you have a wideband in the car?

    Your tune might need small tweaks. Vacuum leaks can throw off some calculations

    No I'm going to order a wide and with my new H-pipe then get it retuned. The guy I took it to is a wizard with 5.0 engines but I've been hearing he's hit or miss with the 4.6s.
    I'm going to take it to a guy I know is really good with SOHC engines and will look it over before it even goes on the rollers.
    Thanks!

    Never shy away from a Ford MAF meter. Get a lightning maf meter instead
