need opinion (help)
 

i just put 3.42 gears, mid length headers, exhaust and intake on my car. i was going to get my pcm tune by madz28 but i think i have some leaking injectors, so i was going to replace them with like one size bigger. what would that be? and would it help if i did go bigger. Another problem i have is that my car feels like it stops pulling around 5000 rpms but it doesnt shift until like 5800 rpms and it is an automatic. i was wondering would it hurt if i got him to set the shift point at like 5100 rpms? would it hurt my trap speed in the quarter? any advice will help thanks?

One injector size bigger is 26lbs/hr, and no it will not help unless you are making over 350bhp. Just because it "feels" like it is dropping off after 5000 does not mean it is. Leave the shift points at the stock points.
