Theres a small typo though

Thick Solid: Tuned with BPB
Thin Solid: Tuned with BPB
Small Dashed: Tuned w/o BPB
Large Dashes: Untuned w/o BPB

Thin line should say Untuned

Thanks for the heads up! That could have been confusing. Lol

FI air flow is different as you have a positive pressure differential vs the engine pulling. It'd also just a lot of work to get solid data when you have sketching such as a turbo that has so many variables. If I was supercharged still I would give it a whirl to see what it was like.

Where is the 116 and 119whp coming from if stock is 130whp?

Some of your numbers don't make sense.

Someone else answered you but just to clarify 130 was the "peak hp" of the baseline. I was showing examples of gains at a specific rpm as the peak number shows little. Especially when you consider both the tuned with and without the spacers made nearly the same peak whp but the dyno with the Crawford spacers has more torque and more usable power.

Nelsmar is right in saying we should be looking at percentages, but what is right here? does the car have 140whp or 180whp? Why would we believe one or the other? why isn't this a standard calculation?

anyways.. looks great. thanks neslmar. where is jamesm when you need him for supportive context

I have a link I will try to post in the morning explaining dynos. This is why baselines and average baseline numbers are very important. This is why there has been friction with me and many vendors in the past when asking for detailed dyno info because peak numbers without an appropriate baseline is hard to gather solid info from. A fee vendors have made as much effort as me to show baselines and it is quite appreciated by those of us that are comfortable with them.

But as for which is right... The maha is extremely accurate and does a wind down to get a crank power reading but regardless that is still only so accurate. Simple answer is none are right. Look at the gains not the actual number tins worthless.
