[QUOTE="LEE93COBRA, post: 3889887, member: 94"] Maf's with 42's and 60's were/are 3.5" Pro-M univers. My cam with both setups is a AFM B-31 grind which is .544 lift intake/exhaust and fast ramp up. Can't remember the lobe center and duration on this cam. My combo with the 42# injectors was AFR 165's, .030 over shortblock, B-31 cam, Procharger D-1R and the first pro-m univer, stock t/b, stock intakes. Never had a problem with bucking. Since I upgraded to the Sieman Deka 60's and changed my univer out for another univer (no other changes) I have had a bucking problem when at steady cruise (1800-2500 rpm) Actually you can feel it a little bit, when coasting in gear at hwy speeds with my foot off the throttle. If you try to maintain a steady speed it will buck and as soon as you tip the the throttle a little it goes away. I am pulling my engine to teardown very soon to inspect some things and then I am going to send the univer off for a recal/test. When i get everything back together I am going to get back started EEC tuning again [/QUOTE]
