Question on HP numbers

[sikcobra03]

OK, so last time I had my car tuned it had a whopping 30 miles on a brand new engine and a conservative 91 octane tune. Since then I have moved the car to NC where 93 octane is sold everywhere and I have put about 4 thousand miles on the car. I still have another thousand until I change to synthetic and have the car re-tuned. Here is my question. How much do you think my HP/TQ will increase with the broken in motor and a more aggressive 93 octane tune?

The pumps say it is 93 octane but you never know what you are putting into your car! I doubt if the 93 octane at mobile or sunoco was tested it wouldnt read 93.

I think the broken un motor may yield 5-10 more HP/TQ. You are going to get most of your gains by re-tuning for 93 octane. If you add 3* timing you will probably pick up 20 or so more HP/TQ. So all in all I'd guess around 25-30 HP/TQ increase with the re-tune and break in.
