I was wondering if anyone has any dyno sheets for a stock car, or car with I/H/E on a stock obd2 GSR and then tuned on a AEM EMS. I'm just trying to get an idea how much gains can be had over the stock ecu on very few mods. Thanks for the info.

 

On a stock car with bolt-ons. There's little the EMS can do to make power over most other engine management systems (Hondata, Crome, etc). So you're unlikely to achieve superior results. I have no doubt you'd be able to find power, but if you plan on staying relatively stock, IMO it's not really worth the investment over other engine managment systems.

 

kendall's right, not worth it

 

I would need to be used due to the rules of a race series I plan on running it, where some of those other options aren't doable. I know its all based on the tuner, I'm just trying to get an idea of "hard" numbers, like average 10whp or something like that. My old man is tough sell to set up his race cars.

 

Nobody has put an EMS on a stock GSR tuned it and has a dyno sheet to show power gains? Thats all I'm asking for.

 

well, you can tune the timing map and get some power there. but not much; it depends on car, temp., alt, too many variables to set a standard
if you gonna go stand alone step up to a TRUE speed density system like autronix for example..just my opinion though
