hi there,glocko here,been lapping up the reading for the last couple of weeks,great site.learning heaps cheers lex.....and every one else of course.current project is a 13 foot jet boat 93 1uzh?as in 4wd.have had a few problems tuning with programmes running too rich ,had a heap of fuel pulled out of it which smoothed it out but lost noticable power.have noticed thru other threads i have 220cc injectors ,would this be the source of mixture problems as i think for the mixtures to be so far out,especially at an idle,specs on motor must be different to others.does anyone know ?if so would upgrading to 250cc gain any thing?cant seem to find much info on the engine.am running link computor ,everything else except for manifolds and k&n are stock.also have developed a miss last time out but have new leads coming,hopefully sort it out.am looking foward to lots more great reading, and and up grades..of course.....cheers glocko...... wet stones are as good as water.......ouch!!!!
