Any idea ofpower expectations andif I would benefit fromgetting a 93 Tune over the custom 87 tuneI have? I use my car as a DD and my dyno numbers are below.

I have no idea what to expect in terms of HP/TQ and if I would even notice a difference with a 93 tune. I do remember after I switched to a K&N drop in filter before the CAI the car felt more responsive. Thanks!

Not sure about the 87 but I couldn't feel a difference over the custom 93 vs. the custom 91.

 

With intake,93 octane tune, and o/r x i put down 300rwhp/318rwtq in the texas heat + 20" wheels.

 

For me, the difference from 87 custom to 93 custom isn't as noticeable as going from stock 87 to custom 87. What I do notice between custom tunes is differences in how she winds up in the lower and upper RPM ranges. For street use I prefer my 89 tune to my 93 tune. If I was racing I'd definately use the 93.

 

You will see from 2-5HP increase in the 87 to 89, same for 89 to 93.
So in your case, it should be between 4-10HP increase.
I'm assuming you'll also be getting the 93 custom tune.

 

CorrectI will be getting a custom tune, think I will feel a 5-6 HP difference?

 

Ya I just put my 93 tune in tonight, after using my 87 tune for over a year. It didn't really feel any faster, but maybe a little bit more responsive.

 

According to Doug, the figures you mention are just about correct. He did say there is close to a 10-12 RWHP difference between the 87 and 93.
