I was told that this might be a spark issue so that's why I'm posting in here. Here is the scenario:

I have made 5 passes on the track, 2 last season, and 3 this past Friday. Last season I couldn't rev past 6k rpm in 4th gear(over-drive) and the car wouldn't go over 99mph. I attributed that to having a blown turbo, or so I thought. I just went back to the track this past weekend with my new 18g and the same thing happened on all three runs. The car won't rev past 6k and wouldn't go over 103mph. Again, this is only in 4th gear in my auto 95 talon.

I have ALL the supporting mods needed to run my set-up and I am running a chip from Keydiver. This is what Jeff told me: "Your engine is going to be under very heavy load in 4th gear. Are you sure that it isn't something like the spark breaking down instead? Have you tried new plugs or regapping them to a smaller gap?
> Jeff O."

The only other thing that might factor in is my fuel pressure. I have an AWD so I have the saddlebag fuel tank. For that reason I cant set my fuel pressure any lower than about 50psi at idle. Somebody, please help me out.
