Should I Retard My Timing??? (Quick, But Important, Please Reply Soon)
 

I Have A Bad *** Exhayst Leak, So I Cant Hear For Detonation, But My Timing Is At 14* On 91 Octane, Should I Be Alright???

I hate to say it, but if your exhaust leak is that bad, you should not be driving it. So no, you won't be alright.

Take care,

;) tell it like it is:p

1) Get the exhaust issue fixed.

2) Now, listen for any detonation. If you have any, back down the timing. FWIW, when I was near stock, I ran 14 degrees with 93/94 octane without any detonation. With my TFS TW's, I run 16-17 degrees with 94 and still no detonation.
