Should i get a MAFT for when i do my headers? Thats the question. will i lean out when i do my headers, or will it be ok. i am installing SLP's. and also, i dont know if it really matters, but i ported out my MAF too (M6). thanks. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Re: Should i get a MAFT for when i do my headers? The headers will most likely make the car go rich, my bolt-on '99 was VERY rich after the install. Porting your MAF will counteract it a little (lean) but IMHO, yes a MAFT or tuning should be done.

Re: Should i get a MAFT for when i do my headers? I have a 2000 Trans Am, after I installed my Headers, High Flow Cats and Y-Pipe, I threw a code ("Service Engine Soon" light came on). P0430: Catalyst Effciency Below Threshold Bank 2. I guess it means that the O2 sensors don't have enough back pressure for the computer to read. I'm not the only one with this problem. I guess a few other people that I know of, have this problem. I've talked to a few people and they said I'm going to have to tune my computer. I'm telling you this so if/when your car throws the code or a similar one, your not supprised. Also, my car is running richer as of now.

Re: Should i get a MAFT for when i do my headers? Not backpressure per se, they don't have enough
temperature to work efficiently due to the sum of
lower local pressure (PV=nRT), more distant
location of the sensors and high surface area
for heat dump making things much cooler (inside
the pipe) than a stock manifold sensor location.
If you could run the O2 sensors' heater power full
time, you might get better results. This would be
some minor surgery on the harness and might annoy
the computer, I dunno.
