Has anybody got any ideas what my be causing my S14a to be jerky and hesitant from around 5,000 RPM and above but only in 1st and 2nd gear?
Pulls cleanly in 3rd, 4th and 5th.
Very strange.
Thanks in advance.

What’s the spec? Standard car has a reduced boost level in first and second. What spark plugs are you running and what gap? What fuel pump?
1998 Nissan 200sx s14a , 2000 std 5 speed with nismo supercoppermix clutch bn6 Sapphire Blue
It is running stage 1a H-Dev with all supporting mods and NGK Iridium BKR7EIX.
Thanks

Hello mate does it backfire at all when it hesitates? Mine used to do that at around, 5k turned out to be knock sensor detecting a knock and cutting timing.
It doesn’t appear to back fire.
