I believe you have something different. If you want to change the operating parameters, you need a new chip.
With Tweecer you can modify it using your laptop.
Tweecer is a good system but complex for a non-experienced use. The newer systems make it less complex to do yourself.

Might be different software or something. It seems they both are pretty much a chiptune that is flashed to modify the stock ecu. My tuner uses his laptop to make changes as well

The SCT is the hands-down choice for me. I've been down the used MAF road and have chosen to participate no further. LoL

The stock fuel rails are suspect at that power level.

I'm looking at a set of new FR 55's at a good price for this setup that I'm thinking about getting. It seems they will support 550-650 at the wheels. The guy selling says for the GT500 they are for they support 760 and those are stock on the 2020's. I spent between $435 and 450 for new Deats 60's. He's asking 240 but I might can get them for $200. either price looks like a steal lol.

Thoughts?

This is what I asked google-

doing a supercharger add to my 95 mustang gt 331 stroker build street car which fuel injector is better to go with the ford racing 55 lb hr injectors or the 630cc - LS1 /LS6, Mustang GT, SVT Lightning 60 lb hr fuel injectors

For a supercharged 331 stroker street car, the 60 lb/hr (630cc) injectors are likely the better choice, providing a safer margin for higher horsepower (500–600+ HP) compared to 55 lb/hr, especially if running high boost or planning for E85. Ford Racing injectors are preferred for their reliable OEM data, which makes tuning a 1995 Mustang significantly easier.

• Why 60 lb/hr (630cc): Offers better "overhead" for safety. Street cars often benefit from this capacity to avoid running the injectors at high duty cycles.
• Why Ford Racing/High-Quality: Avoid generic or knock-off injectors. Proper, reputable injectors (like those available at Lethal Performance) provide the exact data needed for your ECU.
• Compatibility: Ensure you select the correct connector type for your 1995 Mustang (likely EV1, but sometimes updated to USCar/EV6) and use adapters.

Note: For a 331 stroker with a supercharger on pump gas, 55–60 lb/hr is a good street range, but ensure your tuner confirms based on your specific power goals.

The main thing I'm wondering is if the single hole design of the 60's is as good as the dual cone of the 55? The price of $200-230-240 of the 55's is a lot better than the $450 ish of the 60's lol. That 450 ish is on black friday as well, regular price is $539 but they would give me military.

This is the answer, right here.

If the 60s you are referring to are OEM or FMS, then they're fine. Same with the 55s.

Either one will deliver what you need for pump gas.

Deatschwerks 60's, the same ones I just put on the 94 with the vortech.

Called a performance shop near me and he basically said either will work fine but the FR at the much cheaper price will even probably work better overall with the stock ecu. My main question was the single hole of the '60s versus The duel of the 55s but it seems at a certain horsepower level and specially with boost, fuel atomization and everything kind of goes out the window so to speak. I'll go with the 55s more than likely if he accepts 200 especially
