Tweecer is just a bit advanced for most of your average DIY types. Steep learning curve.

26 lb/hr?? Never heard of that size, do you know what fuel pressure that number is at? Are they blue top? If so, they're 24lb/hr injectors. The 30lb/hr 's I have, have a black top.

I have heard conflicting opinions on the effectiveness of running a MAF 'calibrated' to a specific injector size. Without actually going into the EEC program and changing the injector scalars, I think all your doing is fooling the EEC. I don't know how well this method works in all conditions (idle, tip-in, part throttle, WOT, high vs low engine load, etc.) or with non-mustang truck EECs.

I have a 76mm C&L meter with the swappable 'calibration tubes', one tube for 19's and 24's but I'm not sure if I trust it enough to run 24s with the 'calibrated' meter and no additional EEC tuning.
