20psi on pump gas with walbro and stock injectors?

 

bump the boost up to 22 and shoot for 11.5-11.0

 

I think lean is mean. I tune for 11.7 or so +/-...doesnt seem that 11.9 has hurt me yet either.

Also depends on what fuel...Pump, Pump/meth, E85, E98, C16 (any racegas really), diesel...okay not really on the diesel.

 

12.50-12.0 during spool, 11.7@pk boost, tapering to 11.1 by redline, pretty much 11.3 average. This is on AZ 91 pisstane. On 100 octane for drags 11.9-12.0 average.

 

I usually do the same. Its richer than I prefer for my OWN tune when its dialed in, but it leaves some room for inconsistencies in gas quality from station to station for a good,safe tune. It also helps keep things safe thru climate changes.

 

This is still a tick too rich for me but I didn't have time to dial in the tune.....

 

you getting pretty close to the line there dan

 

Wow. This on 93oct?

 

I've ran it leaner on pump and race gas .

 

I run 11.8-12.0 afr on 93 - seems to love it

 

Lol

 

is this the "i have bigger ***** cause i run my car leaner" thread???

lol

<--- nice and safe 11.0-11.3 on 93 oct

 

 

11.3-11.7 for a street driven car. low to mid 12's for a perfect tuned race car

 

Na its more like both my cars run MUCH better with the proper AFR and have MUCH less ignition issues all the while being easier to tune and more consistent from day to day.
