Top end

[IceDragon]

So i am running an awesome bottom end, and a pretty nice mid end... I accelerate really well, and I have a short shifter that seriously, i have to try to make it not spin tires going into second... the problem is... my top speed used to be 121... its now like... 95-100... what is the problem??? I am running a 3 inch intake thats been re routed to right behind the headlight, I have a highflow cat, a K&N Highflow filter, and a 2.5inch catback... I also have my fuel at -20% all ranges, and a +15 degree timing advance at all ranges... what though would make me loose my top end like that??? or is it the gas starvation I am giving my engine cause I am on low money.

your lean. if oyu have your injectors which are not big to begin with set at -20% your leaning out up top. you only have 240cc injectors in that car to begin with, nto very big. then all the mods oyu have done, your not far away from having to upgrade the injectors.

once oyu get your header,and go cams your upgrading your injectors dude. youll need 390cc injectors then you can turn em down a bit. turn your injectors back to default and see what happens. i bet you get some top end back.
