Take it to the dyno and see for yourself... I've got no problem with being proven wrong...

On a related note: I have the MAF bases cut from the airbox (i.e., plastic tube with base) and would happily sell them to you if you don't want to cut your airbox up. PM me if you want them. I can provide pics if you want too.

Well I agree with them not moving much because they don't move under wot. When the motor rocks back under load it stays there. The MAF should see no change. Now during a shift or let off, yes, there should be huge swing in the pipe because the motor relaxed. Unless you're seeing voltage changes on the street and messing things up, ill never know. I don't do dyno's. they are pointless to me and I hate them. I use road dyno software that can calculate the weight of the car, aero dynamics, wheel diameter size, tire size, looks at wot, speed, rpm, etc etc and can tell you a real, true hp and tq since it can calculate the time it took you to go from say 2000 rpm to 7500 rpm. Its actually accurate because you have real wind pushing against you, ambient temps and not 300 degree dyno rooms, and real world roads. Only thing you must do is get all the info right, wheels, weight, etc. also find a flat road and dyno in both directions and average runs for a correct hp and tq. Normally these run like or lower than a mustang but is proven with 1/4 times and trap speeds.

Thanks for the heads up though. We'll watch the volts.
