Who provides the best ECU tune in the So Cal, Los Angeles area? And is a GIAC tune any good?

 

You have two of the best in your backyard...Mynes and RMW

 

RMW? Any idea what I am looking at $$$ for a tune?

 

300-350 i think.

 

$500 for an R56... includes dyno

 

plus any minor updates Jan decides on releasing after you get your tune. I don't have any personal experience with Mynes (but I've read good things), but Jan's tune is...what's the word?...EPIC.

Oh BTW, I paid $500 for the tune, plus $110 for the dyno time (plus $369 for the OBDII flash tool). Money well spent.

 

Stick with Jan at RMW. He can get you as much as this for $600 in an R56: https://www.northamericanmotoring.co...16-post41.html.

 

That link is broken, JumpingJack...but here's another one (maybe not as good).

Thanks for the info! I have a R53 with a 15% pulley, CAI, One ball exh. What do you think I can expect from a tune.

 

It was broke; I fixed it.

 

The tune for the R53 is cheaper (I forget how much) and a quick search turned up some user experiences like this one.

You can expect close to 200 hp with some nice torque gains. Jan tuned my car 2 years ago, and its perfect. Make sure you have a fresh drive belt and spark plugs, also that you have no vacuum/boost leaks.

 

I've had both tuners do my car, by far my favorite was Mynes. Excellent work, realistic advice, no hard sale for more bling.
