I need help tuning this car. Everything is stock. The customer wants us to get some more hp out of it. Ive made some slight changes with no results. A question i have is there any way to change the commanded afr. Wot between 4000 to 6000 rpm its reading 11.76. That seems rich on a stock tune on a vehicle without a super charger. Any help would be appreciated. Thanks.
Yes, that's rich. Aim for mid 12's commanded and make it match the wideband.
if your looking for large gains in hp there really isnt much without bolt ons. the factory cal is pretty stout. there are pickups with timing and fuel, but not a ton. most improvements arent with hp, but in how the car feels and drives. getting them to shift properly makes all the difference in the world, matching shift speeds to the powerband gives a huge improvement as well.
