Default Quantum auto tune opinion

Anyone on the fence about getting anything from them dont hesitate I had some questions about the ecu tune I had gotten and they answered my questions right away within a 20 minute window. On top of it they knew gear ratios, line pressure as well as a bunch of other stuff that pertains to the cars and the products they sell.

There tune for the headers and exhaust is great the car is very responsive shifts more crisply and overall is a night and day difference. I highly recommended getting a reflashed ecu you will make your older car drive like a modern one and get rid of the vague/lazy/detached feeling the transmission has. Gas mileage has also improved slightly the power delivery is also smoother and my idle is not as choppy sounding on cold starts.

I might need to do this because the laggy throttle response and shifts gets old quick in stop and good traffic

I have it for both the 430s, about .2 faster in the 1/4 vs stock but more importantly they drive far better/directly. Plus as you saw the slightly increased MPG

I got their improved throttle curve mapped to my 'power' setting and it's most certainly more responsive and shifts far faster than it did before. That said, the throttle response is a bit sensitive off the top for my tastes.

For the other guys that have it, do you guys have the 6sp or 5sp trans?

I have the 6spd 6th doesnt engage till around 60ish mph as a cruising gear for the highway, I like had them set the tune for normal so the car is always doing the same thing.

Yah its night and day the car feels like it has another 30 hp cant wait to put the supercharger on, and a upgraded valve body. He said the cars are so sluggish because they have the line pressure way down as well as some other stuff, overall best mod you can do to the car in my opinion.

They actually will do 93 if you ask for it, sometimes it can be an issue though so their basic tune is for 91/93 AKN in but they use RON 98 notation since most of the world uses that
