: Fueling problem 316 1.8lt

Hi all,
Ive got a problem that I need some help on. Ive just changed my carb to a brand new direct replacement weber 32/34 DMTL and its running very weak, 82 bhp on the dyno (flywheel). The tuner sais it needs re-jetting, power falls away after 3500 rpm and engine just dosent want to rev. Do I need to replace my mechanical fuel pump and is this the only fuel pump on the car? Please help as it was running ok before I changed the carb!!
