Here are the dyno results for the Diablosport InTune 1-1000 tuner. The tunes are for 87/91/93 octane what do you think about these numbers?

They look pretty good but I'm trying to see what the big deal is. I thought most of the people with 3 bar tunes sit somewhere around 360-380whp and 450-475wtq....So these dyno curves look industry standard to me.....
You can make some timing adjustments and some fuel adjustments but basically X amount of boost with Y amount of spark will yield similar power numbers....Considering for the most part that all things being equal in the SHO are, as far as compression, turbos.
One of these days I still want to do some pulls in my car I just haven't had time and I still have a couple things that are bugging the **** out of me in my tune that I can't figure out but I'm getting close I think.
I want' to see what 20-23 psi without meth puts down on a dyno jet

They can hold 22 all day long.....efficiency degrades badly I'm sure...but I'd like to see how badly...And I think really the limitation is the fuel and I'm not talking about the volume of fuel....I've heard people here say that power is down when you up the boost...That's definitely true because with pump gas you have to run really low timing at 22 psi to avoid pre ignition.....Well no surprise when timing is down so is power so it makes me second guess saying that the turbos become terribly inefficient at elevated boost.
Regular fuel is how I run now at those boost levels....I would like to add a 3-5 degrees timing and use VP street blaze as a race tune...That fuel has a similar stoic point to pump E10 fuel of about 14.1 ish or so. So fuel delivery should not be as much of a problem as the higher E fuels due to their stoich being like 9 something or whatever E85 is
Yeah I figured you were messing with me lol.
I haven't messed with any corn or meth. Just 93 Sunoco that is up to E10 supposedly. It's a busy station around me and the only one I use as it seems to be reliable.
I really don't know how to scale the tune properly for higher E content and make the stft's level off...There are things I could do such as add fuel globally to the tune but that's not really the correct way. You need to change the slopes and intercepts and the MAP sensor and I don't know which way to change them. And I know at high boost levels my fuel pressure would drop too much as it already gets scary low with normal gas....I think the corn is best for moderate boost and allows you more spark advance but when you push boost to the maxx you we just can't get the volume of fuel from our fuel system alone....my main problem at the high boost is the fuel pressure not pre ignition resistance
WIth these new ECM's and all the things you can change sometimes there is more than 1 way to get a result but it's not always the correct way and I 've had the bandaid changes made to my tunes before and I was told that it was the way to go then other tuners showed me the light lol....They pointed out what was wrong and the proper way to do things....That's why I got into my own tuning because I've paid pros before then had other pros tell me my tune was all jacked up....It can be hard to know who is telling the truth but a couple that I've worked with actually took the time to show me why what the other tuner did wasn't right or how it was inadequate.
That experience was from my mustang not the SHO
