hello to all the members and concragulations for your site.i am the owner of a 5 gtt the last 17 years and now i have my 4th 5 gtt.

i would like little help with afr problem i have.i have just finished my rebuild on c1j and until 3.000 rpm everything is ok.when i push the pedal and the turbo comes in i feel the engine hezitating and i see on the wide band afr 16-17.all these with t-2.5 and std engine @1.0 bar presure.i turn of the turbo pressure @ 0.8 and still i have afr 14/15

my carb is std with 120 main jet 100a/c 100first stage and normal 2nd stage.
