Well today I took my truck down to the new SuperFlo dyno in Greeley to try out these new Don M injectors, and all I can say is "WOW" these things rock. Back in February when I dynoed I was only able to muster 460hp with stock injectors if I remember right, and today my best reading was 593. 9hp and 1143. 9 torque (Dynojet numbers) and 561. 7 and 1081. 7 (SuperFlo numbers) these are corrected and I am still grinning from ear to ear. Thanks Don M for a top notch injector and Laser Bob for a great install, I cant wait to see what I put down with these new twins. Mike
