I don't know what it is with the Vararam that these dyno results turn out so poor! Everyone raves about the throttle response, crisp acceleration, and overall good performance but they just don't do well on the dyno! I have first hand experience now with the VR and I have to say I'm sold on the crisp throttle response! I just don't think that dyno'ing the VR is the proper way to evaluate it. The proof really lies in the 1/4 mile, 0-60, ad 60' times that the VR seems to excell in.

I have been evaluating a VR for the past week but I don't race so I don't have hard figures and scientific proof of performance. I installed it just to see if there is any difference between it and the CAI I just installed. I can say this, the VR has a much better street feel and is more fun to drive around. The low end response is, and I keep saying this, CRISP and clean, especially in the low to mid rpm range. The CAI seems to lag a little until it hits 3500 rpm then takes off like a rocket! The only factor that has me worried a little is that I'm running the VR on a JRE 415 tune which is calibrated for the CAI. I really don't know if I'm running too lean with the VR, although the ltft's are within range.

Everyone seems to be hell bent on dyno results showing huge gains and such but for me it's all about driveability, throttle response, and smooth linear acceleration! The VR seems to deliver on all counts. The only driveability issue I have right now is slight surging at low cruising speeds but I also get that with the CAI! I'm going to change the plugs, wires, and MAF as suggested by a couple pro LS3 guys.

I know a couple of you guys had a VR, switched it out for another brand due to poor dyno results, then switched back to the VR! There's just something about it that we are all having a hard time putting our finger on!
