So, I got my truck tuned after the MP122 install and this is what I have come up with. To me, these #ers look low but the graph looks ok I think. The Afr was 11.1 through the hole pull so it is on the safe side. All mods to date are in my sig. Any thoughts or comments welcome.

 

how much boost are you running? im sure there was another 30-40hp if u took it all the way to 6k.. those 4.10 gears are lowering the powerband as well, but numbers are just numbers!

 

I was getting 7.5psi boost on those pulls. While driving and pushing it wot into the 5900rpm shifts i was seeing 9psi.

 

what is STP correction Looks low to me too. I'd think there's a lot left on the table. Is Lyndon tuning at his pace or by mail order?

 

STP is the power correction standard he used on the dyno pulls. He was tuning in house between pulls. Im not so worried about the #ers but more about what the graph looks like. I dont have much experience with reading these and was looking for some thoughts on how it look's.

 

Well most charts and numbers are done in std correction. Your numbers and power curve look nice. Headders would be worth quite a bit. You running e-fans? Have you modified your volent air box? There is more there but I'd b happy with that.
