What is your setup?

Re: car bogging
 

390cc injectors, t25 turbo, intercooled, 4psi saab bov ssac mani. flywheel clutch

Hm damn, I was hoping you have that problem with your stock one. For over two years my stock car will randomly bog through acceleration and I've replace wires, plugs, ignition coil, dizzy cap/rotor, fuel filter, etc...there's no "pattern" to it, just does it when it pleases while I accelerate and it's annoying as hell.

Maybe it's your map?

thats what im thinkin it is i think i might go "borrow" one from the junk yard.

with the stock ecu my lil bro took out my car and still beat a impreza 2.5rs pushin 10psi..... just got back from cruzin

Re: car bogging
 

I would look at two things on the BIN:

1. Fuel supply - more fuel needed within the rpm range that it boggs
2. Ignition timimg

If you haven't tuned it yet, you should do so now.

My 2 cents.

i was thinkin that i was getting to much fuel, because with the chipped ecu i get alot of smoke coming from my exhaust....

Re: car bogging
 

Mine would bogg sometimes but higher up in the RPM. When I add more fuel the bogging stops but I get a little back fire (popping in the exhaust) when cruising which is the result of a little too much fuel.

You can remove some fuel and see what happens. If that does not solve the problem, add some fuel.

how would i remove fuel?? i was thinkin about using my stock injectors again
