So I have a question about my 99 GT. I've had it about half a year now, gotten it all tuned up etc, and it just seems like it doesn't have much pull above 5k RPMs. 3-5k it pulls like crazy, and from the other 3 Celicas I've had I know the 5sfe is no powerhouse, and has more power in the midrange, but it seems like I'm really lacking here. No mechanical problems, up to date on maintenance, oil changes, etc.
Is there also a difference between the OBD I and OBD II cars in performance? -------------------- 1999 Celica GT

The valve angle seems to be the problem, the valves are too "flat" against the piston versus high flowing pentroof head found in higher performance engine (like the GE heads)... DEAD END for torque at high RPM
