Tuning my car... a couple Qs.
I have an SAFC, an AEM Tru Boost, and an Innovate LM-1. Noted fuel mods are Walbro fuel pump.
I have my Tru Boost set to 65% duty cycle which is roughly 9.9psi in 4th and creeps to like 10.2 in 5th. Perfect boost for the stock turbo/intercooler combo. I hit full boost somewhere around 5k. My SAFC hi map currently has no correction until 3k. Than at each 1k interval it is +5 (3k) +5 (4k) +10 (5k) +0 (6k) and +0 at (7k). This causes my AFRs to be a DEAD 11.7-11.9 until about 6k when it than becomes a 10.2. My question is, what is causing me to run so rich up top? Can I safely turn the fuel down? Do I have upgraded secondaries? |

spray carb cleaner around the secondary rail and see if idle speed increases.

wouldn't the extra fuel pressure from the walbro make it run richer up top?
