I tried e-mailing you but never got a response.

What are some typical gains by tuning for 91+ octane gasoline? Also, can you lean out the A/F ratio on my '95 Z28 so that I could see a few extra HP?

I'm sure I'll have a few more questions for ya!

Thanks!

 

13 rwhp is the minimum for your basic power tune, I think. And Ion automatically leans out the A/F ratio a little bit. That and ignition advances are the two ways he uses to get the extra power.

 

That is correct. Thanks for answering that for me.

Doug,
the only email I ever received from you (and replied) was when you asked me about filling out the tuning order sheet. That was on 11/22 and I replied it the same day.

 

I sent another the same day but if you didn't get it then no big deal. Do you advise tuning for 91+ octane gas for maximum gain with one of your tunes? Out of the 13hp, how much do you think it's worth by itself?

Looking at the mods in my sig, would I still see ~13hp gain with a tune from you?
