First you should check your Air/Fuel Ratio on a Dyno or with a Wideband Sensor. Than you can see if your engine is running in a safe range.
After you changed to a 7 PSI Pulley do this test again and if necessary you need to compensate the now leaner Air/Fuel Rate with an E-Manage or AEM EMS. You can use your stock injectors, but you should control the duty cycle from them (managable with a E-Manage or EMS), if both the AFR and the Injector Cycle is i a safe range you should be ok. Otherwise you need bigger injectors and get rid of the Comptech FMU.
