I'm experiencing a problem. The car over the past couple weeks seems to not be as powerful as it was when I first got it running. (it's L98) Not that the car isn't fast, it just seems that it's lagging. For example, when I got the car running right, I would go at WOT and the car would pull and pull and pull... now, at WOT the car still accelerates strong, but not like it did. I checked my fuel pressure, it's good. I checked the timing, it's sitting at 7 or 8 degrees BTDC. I know the factory setting is 6, would this be causing that much of a problem?

All ignition parts, etc. are new. (plugs wires cap rotor etc.)

any insight would be appreciated.

 

Seriously, run the car on a gtech or at the track. I do not trust the accuracy of your butt dyno.

 

Where do I find a Gtech? That's another thing I'm thinkin too, it may just be in my head.

 

Track times or dynos don't lie... check your car out!

 

You're right there... my only problem is that I know of NONE in my area. I've looked . I'll keep searching though.

 

You might try increasing your timing. I know my car was fond of 10 degrees. It once went much higher than that and didn't have a problem. But I backed it down to be on the safe side. That and it got crappy fuel economy.

 

I'll have to give that a shot. My timing light's on the fritz, so I'll have to wait. I heard another person tell me their TPI liked 10 degrees as well... coincidence? I think not.
