ok so i have a 94 gt that i havnt driven in a year or so because of school and what not but im getting back into it finally but i have a few problems, its a hci 306 with a 190 fuel pump 24 lb injectors 5 speed swap ect. One is that i have a really bad vibration in the shifter around 90 mph and up, i noticed that one of my wheel bearings is starting to make noise but i would think that would be more in the steering wheel if it was that.

second i got it tuned awhile back and the injectors were running at like 95 % duty cycle so he suggested i just went to 42 lb/ hr and a lightning MAF but it doesnt seem like anyone has these anymore, i plan on eventualy having around 550 to the wheels mayb a bit less with a 331 on boost, so would 42s support that or could i go to 60's but then it would probably be too big for my current 300hp set up right?

sorry for ranting but all help is awesome

thanks
cory

well a 190 with 24's should support 400

so, i'd get a second opinion because 60's are HUGE

well hes a very very well know tuner, mayb the injectors are bad? i got them off ebay and there white tops but i ran the numbers and they are 24#ers

live4motocross11

advice? they were running like 98% duty cycle when he had it on the dyno if i remember correctly

i dont wanna keep spending all this money on dyno time and waisting it

90% is a little high, your injectors shouldnt be running over 80% you probably need new injectors probably 30lbs

AdderMk2

he only needs 24# injectors. His combo doesnt make nearly enough power to justify 30#ers.

then why am i maxing them out adder? im just looking for help, it has 24# tan top injectors in it according to the numbers F5te-c1a
