Yeah I believe it was like 430/380 and after it was 472/406. This was on a literal brand new installed and Dynojet calibrated hub dyno.
42hp gain on 93
You’re twice as good as everyone else
Wow

How does 125mph fit you? Because that’s the typical e85 tune/dr time I see with my folks. That work or nah?
that would be awesome, that is the first I’ve seen someone trapping 125 plus with just a tune.

I’d still need to actually see it to believe it.

Not a gen4 but a gen3 I just did I have a quick video of. He’s got a JLT and gutted cats and a drag pack on my e85 tune.



The gen4 responds better and moves more air than a gen3 with JLT intake tho.

Ok. Here’s the dyno video and all the data. And it was 440 stock not 430- correction. Again brand new Dynojet hub dyno just calibrated by Dynojet.

Sorry but you'd be the only tuner ive ever heard of see those gains with just a 93 tune on a stock GT. And you'll forgive me if I dont take your word for it after the whole Lane Centering debacle.

Yeah I was wrong about a feature. Forget about all the other facts and help I’ve dropped on this forum for free. You believe what you want but you got all the data right here. And tuning development didn’t stop a week after it came out. I’ve put thousands of hours and miles into tuning dev for the s650 and you’re seeing the fruits of those labors. Check out my TikTok page. I’ve posted hundreds of videos of only my customers cars running my tunes. Nobody else’s. So please forgive me for the lane centering mistake. But make no mistake that has absolutely nothing to do with tuning and tuning on these cars. I know very well.

Furthermore if you already have an RTD4, I’ll send you a free power tune to test and you can tell me yourself what it feels like. I’ve done that more than a few times. And shortly after I’m taking payment for the rest of the tunes I offer. Happens every time.

Don't forget the rear diff cooler on PP GT cars... lol
Or that Flex tunes don't work.
You spit out lots of BS man.
And it's always the .... I've tuned thousands of cars and you guys are lucky I grace you with my presence on this forum...
Your ego is massive

Would you send me a tune? :angel:Or just AZ_Ryan? I was gonna buy a new RTD4 obd but been just procrastinating about it but this might actually get me to pull the trigger.

Yeah you get an RTD4 and I’ll send you a 93 or e85 power tune. Your choice.
