Hope someone here can help me out. As posted just restored a TTA, the engine is rebuilt, roller, not sure on specs, car shifts fine, SM readings look good, and been driving the car around for 4 or so weeks now.

Running 16#'s, with no knock. My problem is that the car shifts strong and the tranny is rebuilt, between the engine and tranny the previous owner said he spent 10k +.

Question is 1-3 gears shifts fine, but to get it into 4th gear, I would have to get to 90mph, and about 5k rpm. Then when in 4th gas mileage is great. But every time I would have to do this to get it in 4th. Not a big problem as its almost all highway here, but it is 30mph over speed limit.

Some mods are...

TT Chip
60# injectors
3" TBE no cat
External WG w/ manual boost controller
Fan switch
Hot wire kit, FP not sure but previous owner said FP has been changed
Stall not sure but best guess 2800
Highway @ 65 Blm's are at 118-122 cruising

Any help will be greatly appreciated,
Marcel :)
