I tuned a friends evo 8 with only downpipe stock exhaust and boost controller and tune and i hit 317 at the wheels at turbochargers

 

Go with Hellcat if you want a good tune for a decent price . I can't wait to go back to you for my 2nd tune Carl . - Vinh

 

New Dyno at different shop

 

update above

 

put more mods in then get one tune. Make sure he's a good tuner and quick. Some tuner take their time, but that doesnt mean he's good. I changed tuner 4 times already.

 

I'm wondering does an exhaust really make a big difference in a Tune

 

bout 15 whp

 

For the guy wanting to know what an exhaust alone gains

You really should use one dyno and stick to it.

 

That was my plan but that shop didn't seem trustworthy so I went somewhere else for a new baseline. Got the feeling the original place was messing with the settings to show a dangerous a/f reading to scare me into getting it tuned there at their cost of $500. This seemed to be the case after MDR found no a/f spike as shown on the original shop's dyno run. MDR tuned me for a whole lot less and installed a AEM UEGO. The combined price was still lower than $500. They also had better customer service.
