My car pulls all timing at WOT I've been tracking down reasons why my beefed up LT1 doesn't run like similar setups across the internet and realized in a datalog all timing is pulled at WOT do to knock retard.
Can this hurt performance? How can I desensitize the knock sensor.
The engine is a fresh 383 with Roller rockers, custom cam, TFS heads, true duals, with an A4 Edge stall.
And it has a mail order tune from PCMFORLESS

ALL timing? That would be pretty drastic. It would absolutely kill performance. You need to find out if the knock is real or not Try some higher octane fuel and see if it changes. Sensitivity adjustments to knock can be done in the tune.

I'm chasing down other problems so I can't get a dyno tune anytime soon. But I have been emailing Solomon at LT1PCMTuning.com. I think I'm gonna get him to modify my tune a little until I get it dyno'd.
Not to mention not everyone NEEDS a dyno-tune. A mild street cam-only user might not need every ounce of power. Many people aren't willing to pay $400 for a dyno-tune for an extra 10 HP.
Could you tell a huge difference in performance? I was wondering if this could be the reason my car didn't run like I expected.

I'm just not ready for a dyno tune. Seems like I'm having tons of problems everywhere else. The car is a weekend hot rod and I don't have alot of time to work on it. Mail order is the way I had to go to get it driveable last year.
Now I have oil leaks and a belt alignment problem to work on, not to mention my rearend is spinning one freaking tire. Gotta get another posi unit now.
I don't think the dyno tuner will appreciate me pulling up with a rolling pile of junk to start with.

After I fix a few issues I'm having with the car, I'm making an appointment at the local dyno shop. Hopefully next month during vacation I will make it happen.
