It's a 2001 996tt. I have a full turbo back RUF exhaust only. A local tuner is going to give me a great deal on a tune. He thinks about 60-80whp and 80-90wtq.

Should I wait to get a cold air and diverter valves prior to getting it tuned?

Let me know what you guys think.

Thanks! AL

 

I highly recommend that you go with well known tuners on this board, EPL,Protomotive, UMW.

I did the DV;s and tune, That's it.

It make your car go from 116 trap speed to 120ish with a flash. That's a great increment.

 

Silly question. How easy was it to install the diverter valves? Did you have to remove your bumper?

 

Dont forget EVOMS

+1

there are lots of 'tuners' out there, there are only a few really good tuners, go with one of the tried and trusted ones

i went with EPL, car is so much better/smoother/faster now, excellent service as well, Tony really takes care of his customers

 

With the EVOMSit software and your current mods, we can bump the car up about 80hp and 90tq. There are many reasons why I feel the EVOMS software is the way to go, but the proof is in some of the record breaking 996's that are running the software, as well as the number of cars our there running trouble free.

Feel free to contact me if you have any questions, or if you'd like to arrange the tune. Keep in mind that we back the EVOMSit software with a money back guarantee too!

 

Yes EVOMS is very reputable as well.

 

No. Its easy, there is a DIY here somewhere.

 

OP- Cold air intake is a waste of money for your power/flow levels.

WHO is the person who wrote the code for the tune your local guy wants to toss in? With EVOMS, UMW, EPL, you know the person and reputation behind the tune...Tuning is not like a part... you are buying judgment, experience AND follow up support. Cheap tunes are cheap for a reason....

 

^^ Very well said.

 

DIverters a must....I did GIAC no problems

 

PS...no cheap shops.....specialist only!!

 

apparently its very easy if you have very small oompah loompah munchkin hands...theres not much room in the engine bay, i think i read most shops will charge approx $200.00 for install

 

i did my diverter valves but i always wonder if i needed too. i haven't noticed the difference.

its a DIY but its a PIA the first time with does damn clamps that face the wrong way.

 

Most of the time you'll only notice a very minor difference from upgraded DV's. Some quicker response, less noise, more reliable. That is....until your stock ones fail. Especially if you're running higher then stock boost levels, the stock DV's will eventually will become unable to handle the boost and fail. The upgraded units are a must for high horsepower applications.

Here's a pic of the EVOMS units. They carry a lifetime warranty.
