What sort of air /fuel ratios are you guys looking for in top gear with a N/A combo?
It's just that the dyno guys like to pull them up through top gear, max load.Ideal AFR is based on a lot of things but what gear the transmission is in isn’t typically one of them.
I am using 98 here in OZ, we leaned it down twice on the dyno and picked up around 30 HP but it was still in the high 11's on the AFR reading, I've gone leaner one more step but it has got soft on the hit and the 60ft. has dropped off, problem is I'm running an 850 TQ and it it doesn't like being that lean on the launch, I've slowed the secondary air door opening down but it's really not happy. I'm trying to source a decent size double pumper to get it to leave the line like it used to.Using e85, at WOT I tune for 0.77-0.82 Lambda. This works the best for my car.
