Tuning 1.3 HC-E

Hi all,

Sorry if this is a dumb question but ever since dropping the new engine in I seem to have a flat spot in first gear where the car kind of lags. I’m thinking that due to my shit labeling and having my vacuum hoses all ass about maybe setting the timing has effected how the car runs - car starts a little rough too.
Question 1) Would the hoses and setting the timing if they were incorrect cause this effect?
Question 2) Is there any data on how to tune ( i thought it was kind of auto tuned lol) I can relate to
Question 3) Does anyone know who would tune this up in ADL??

Thanks in advance
