Default Dyno graph from Protune



Got protuned yesterday at PAS by Dave Brown. Overall, I am fairly happy but thought I'd make a bit more torque with the VF34 and all of the supporting mods. I don't know if it's just me but I felt as though the Cobb OTS map was actually a bit more torquey at lower rpms than the protune result. I've looked at a few dyno graphs with the same setup and most of them seem to have higher torque and hp numbers at a bit lower rpm. Any suggestions on how I can improve that? Mods are VF34, pink injectors, STI TMIC, EBCS, Cobb catted dp, Prodrive axleback, STI uppipe, Cobb AP.

Did Dave say that there was anything odd about the car and/or tune when he was done? It would be worth contacting him to see what his thoughts are and also find out some baseline numbers for his dyno so you have something to compare to. He's a good guy and I'm sure will help you out.

You could also try taking a couple datalogs and throwing them up in this thread. We'd be happy to take a look at them for you to see if anything jumps out.

Thanks Chris , I will do some logs. I didn't get to speak to Dave much because I think he was having a very busy day but he said the car was in fantastic shape and he felt as though we should have gone to around 19psi but I wanted to stay a bit more conservative. The car pulls really well once you move up into the rev range 5000+ but I felt as tough there was a bit more torque available lower down on the rev range with the stock Cobb OTS map. As a matter of fact, I probably would have been very happy just having him optimize that map but since I relatively new to the tuning bit, I wasn't sure if that was possible. Overall, I am pleased but I still want to see if I can get a bit more torque and move the power a bit lower down the rev range. From many of the vf34 tunes I have seen, they seem to be making pretty good power around the 3500-4000 mark.

Hey there this is Ian @ PAS "I wrenched on your car" Im prett sure we thought you were worried about you breaking your tranny as you kept bringing it up. In turn Dave made the transition very smooth. If you want more punch then he can do that too. It sounds like you car reacted too the OTS map rather well. Some do, some do good but not as good.

If you would like too give us a ring, Id think we should be able too get you straightened out.

Not to start a dyno war but we have done everything we can for the most part to make our Mustang Dyno read low low low.

Hope I didnt come off rash as thats not what I meant. I really hope we can get it to where you would like it.

Edit: this was so random for me too find. I just clicked on a random most recent post on the mane forum page. haha

Ian, not at all, I was very happy with everything and the car drives really well but I think I may have read too much on some of these forums as to what a massive difference there would be between the OTS map and a dyno tune. I was worried about the failure of the tranny but Dave assured me that unless it's abused, it should be fine. I did want to speak to Dave a bit more about it but he seemed to have a busy schedule so I will have him retune it again once he suggest s what I need to get the torque up a bit more. Overall however, the guys were very welcoming, and nick said you are a wiz with these cars so that also put me as ease. And yes, I was told by a few that 266 whp on that mustang is a pretty good number so I am more than happy with that.
