Uprev or not?

2013Zsport · 05-07-2014, 06:02 AM

I have an HKS cbe berk HFCs and post maf silicone intakes with drop in filters. I was thinking of getting stillen gen2 intakes to replace the silicones and drop ins. Now can get the car tuned with these mods without getting the up rev flash?

The UpRev flash is the tune so I don't really follow your question.

Side note. If you aren't going CAI, then just stick with your maf tubes.

There is no way to tune without "getting the up rev flash", as you put it.

A tune is useful for throttle response and fan control even without any mods. You don't need a tune for intakes and exhaust, but a tune will take advantage of them better than the stock tune. A tune really helps the car utilize bolt-on mods to their full potential.

I guess you could go with Ecutek instead of Uprev, but that's a entirely different can of worms. And friends don't let friends buy short ram intakes. Stick with what you've got and get an Uprev tune. You don't need to reinvent the wheel.

But if I get uprev can I have a shop just put uprev on the car and call it a day, or do I have to put the car on the dyno and have them calibrate AF along with other things? Someone on the forum was saying after some mods especially intakes the car would run a little on the lean side.

You need to get a dyno tune. That's how the program works. If you don't have access to a dyno, you can log certain parameters, email them to the tuner and he'll change the map based on what your ecu is seeing. A dyno tune is always better than an Etune.

Another problem I have is that I've heard others say they are having problems with emissions after getting uprev is this true?

Chuck33079 · 05-07-2014, 08:31 AM

That depends on your state. Go to your local subforum and ask.

So after buying uprev which is $500, what's an average price for a tune another $500 or so?

Chuck33079 · 05-07-2014, 08:32 AM

It depends. Start calling potential shops. Ask for a recommendation in your local subforum.

Did any of you guys get your cars tuned? If you don't mind telling me what did you pay? Just want to he a basic idea of what I might be spending.

Chuck33079 · 05-07-2014, 09:03 AM

My tuning cost isn't comparable to what you're doing since you're NA and I'm not. I had the Uprev cable for my base map, so I only had to pay for the tune. The tuner took most of the weekend annd built a map from scratch.

curious: what's the problem with short ram intakes? i've got K&M's typhoon...

They pull hot air in from the engine compartment. They're worse than stock. On a dyno you're ok, because the hood's open and the fan is blowing on it. It'll show some gains. In the real world with the hood down, it's a hot air intake. The stock intake is less likely to heat soak since it's not metal, and the airboxes pull cooler air from in front of the radiator support instead of hot underhood air. That's why drop in filters and MAF tubes work so well. You're still getting cool air.
