Re: American racing headers 1 3/4
Cdgatx) Still need tune for it.
MP) Do you have a dyno to test? A tune may not be necessary if the gains are within the limits of the processor to add or remove fuel. If the headers added more HP and TQ, your A/F ratio will lean out. If the processor is within it's limit to adjust fueling to meet the "COMMANDED" LAMBSE, then no tune is needed.
* LAMBSE is the final commanded fuel mixture commanded by the Processor.
Cdgatx) The heads have to be removed to install headers.
MP) That's stinks and it makes the cost of installing even more expensive....oh boy.
Cdgatx) Does feel stronger than before.
MP) I appreciate your impression and I'm going to assume the headers made a significant difference in HP and TQ but it would be nice to see before and after dyno information.
In the end, thanks for sharing.
