Guys, let me throw this out at you one last time. The owner of the blazer is 100% convinced that this is a fuel delivery problem so he wanted me to double check injectors . So, I pulled them and had them flowed and they were great. These are factory truck injectors. And again, what the blazer does is you can crank it and when you intially pull it out of the garage and go to hit yhe brakes it will fall dead. When you re crank it, it will sit and idle absolutely perfect. When you put it in gear and start to drive it, if you gently ease into the gas pedal, it acts as if it is about to bog down but if you drive it very aggressively and wide open it goes, but when you attempt to slow down and stop, it dies. Again, no vacuum leaks, Airtex E3270 fuel pump, stock fuel pressure regulator on truck intake, Hot Cam with 2500 stall.
There is a local tuner that tunes and does conversions, so we are probably about to take it to him. Thanks in advance for any input.
