Im goin to Austin this thursday to have a custom tune done on my car by UPREV . I hope its worth it and from what i hear, it is. Ill be sure to let you guys know how it turns out. Im excited about finally getting my car tuned wish me luck guys!

 

Cool. I'd like to be able to go right to UpRev for a tune, but Florida is a bit far to drive.

What mods do you have done so far?

.

 

I thought they said they were working on a shop in Florida so hopefully you should be able to get something done soon.

 

CAI, motordyne 5/16 spacer, gutted cats, xo2 dual cb exhaust.

 

So how did it go yesterday?

 

they fine tuned the hell out of my car and i only came out with about 5whp over what i went in with. they were not sure why my car didnt want to produce more and were dissappointed with the tune so they gave me a price cut. the car feels much better on the highway because of the way they tuned my throttle response. the but dyno feels like i gained more than 5whp. over all i still think that uprev was worth the money.

 

You may have had more gains in the middle like I did. What does your torque curve look like? Looks like your mod set up is almost exactly like mine except I don't have the gutted cats. What you're feeling may actually be more gains in the middle like mine, even with a small gain in your max. It feels good, doesn't it.

 

This is just a general question. Can Uprev or any of the other flash tuners change the scalars for injectors on a F.I. set up? I just don't want to jack with a laptop type system or paying someone to tune a system...

 

most of the power increase is going to be in midrange area anywhere from 3000rpm-5500 rpm where vq tends to run very lean for some reason especially with mods. Ur car should be a lot faster eventhough u might not gain much at top. For example IS350 only 5-10 peak hp than my car at the same time it wieghs about 150lb more. But pulls on me about car or two from 10-80mph. The only reason is because it makes more power at midrange than our cars. more area u have under the curve faster ur car is.

 

How much was the tune?

 

They can, but I believe to a certain point. I know you can do it for a Turbonetics ST kit, bascially because TN will reflash your ECU for you. I think if you're planning on pulling a certain amount of power our of your car, there is going to be a point where you should go stand alone engine management.
