FAQ
How much power gain should I expect?Race 1 / 120cc typically adds about 50–60 HP over stock with good drivability for towing and daily use.
Will these fit my 1999 truck?If your build date is on or before 12/07/1998 (early ’99) and you have AB code single-shot injectors, yes. Late ’99–2003 trucks are usually AD/AE split-shot.
Do I need tuning?Tuning is not strictly required for mild use, but a quality 7.3L calibration helps maximize power, smoke control, and EGTs.
Is a core required?Yes—an acceptable AB-code core is required for exchange pricing.
