Looking to see what kind of difference bolt-ons really make on these cars. Does anyone have dyno slips and/or time slips showing the results of intake/exhaust/ecu piggyback, etc...?

 

I think I posted some dyno charts from a reflash a while back. 10-12whp on the reflash is typical. It does make a difference that you can feel.

I plan to put mine on the dyno after it's got a little better tune on it. I'm currently running CAI, UPD, headerback exhaust, timing box, and piggyback oh and port And polished intake mani. I'll tell you one thing though after I put that piggy on that car became a whole new car

 

Hopefully your piggy settings stay engaged. I swear my piggy settings weren't staying locked in.

 

The piggyback settings don't change per se.

The ECU has many different maps and values it uses according to operating conditions. For example when the intake air temp is hot it pulls extra timing, when it's cold it adds extra timing. A piggyback can't take these factors into account so it may blindly add timing. On a hot day then your ECU might learn that it's knocking when it shouldn't be so it starts using more conservative settings. As a result your car has become un-tuned until the ECU is reset so it can revert back to the settings from before. The dangerous part is if you advanced the timing and it was already in the conservative mode resetting the ECU may detonate the engine to pieces!

Seems logical. It just didn't have the "xmas effect" anymore on me.

 

Well I would be able to tell if the piggy was not running right. Ever since I installed it ivE had nothing but a huge gain.

 

Maybe it was my tune then..but something didn't seem right and my gas mileage was absolute ****.

 

Well it would make sense to have ur mpg go a lil no? I always figure the more hp u pull out and use your gunna sacrifice some mpg

 

Theoretically yes, but the drop in mpg was crazy though.....I rarely if ever hit MIVEC uz I knew that was a big gas eater.

 

My mpg wen down a bit but not major. Though I dint stomp on the gas like I used to befor haha could have been your tune
