Dyno Retuned!! I decided to go back with Jtran who originally tuned my Altima on his Mustang Dyno. He is a great tuner and his website is jtranstudio.com located in Houston,TX. On the first video which is my base run with whatever tune had came with the car it only pulled 245hp/249tq. At the end of the first video you can see under hood smoking lol. Second video shows my peak run hitting 263hp/386tq I will also scan and post graphs. I havetwo of the them cause he wanted to show me how my car made more power with the tcc unlocked vs when locked which I found very interesting.

Also wanted to clarify that mustang dyno can read nearly 13% lower than common dyno jets in most shops. Info from:
https://ls1tech.com/forums/dynamomet...-dyno-jet.html
So theoretically I would be 297hp/436tq

That second torque number isn't right, thats way high..That's like saying I make more power if I leave my car in first on the dyno. The numbers will read higher with the converter unlocked.

I'm pretty sure they were 2nd gear pulls as I saw the speed on laptop get to about 85+/- mph. Btw he is a very good tuner reason why he gave me the two different graphs comparing the tcc locked and unlocked with tuned vs untuned. I do appreciate your comments!
I'm not doubting his tuning, but showing you the difference between a locked and unlocked converter to inflate power numbers is like saying let see what kind of power it makes on 7 cylinders. It's completely useless information and a waste of your gas and time.

Maybe I'm wording what am I trying to say the wrong way...this was first time he has ever tuned ls4 car, he gave me the graphs for my understanding on why he used played with the tcc lock on hptuners while dyno. This showed me that my car's ecu does better on its own than with manual overrides. He wasn't trying to inflate numbers to impress me, all I worry about is how much is gained under curve. I doubt peak numbers win races. If that was the case, 1800hp and 1600hp supras wouldn't both be 8 sec cars lol

By NO means was I boasting lol I do understand how text can be misunderstood. I had theoretically in bold meaning I have a margin of error. I'm just excited by how much smoother and faster my car feels. I appreciate your consideration in taking it slow on me hahaha
