Well hope GunShyKennedy didn't run over one of those Tasmanian Devils. I think the map is on the way to recovery, but I will let him explain.  One more change and test and maybe he will share. Oh and when the hooch wears off.

Thanks so much for that, now I know what I could get away with, if I change cams from the 57H  :wink:
There's some serious latitude for lift from stock then.
I was led to believe, about 0.600 was the maximum, with stock or 10.5:1 pistons.
Or did I ask the question incorrectly?

Yers, the tuner set the injectors at 4.9.  5.3 injectors are fitted, tuner got it wrong....and he fitted them!

but corrected geometry over .625" ?

Some will spring for corrected geometry, the same folks that will not be worried about trying to get the last dollar out of the stock springs.
I have not ever run stock springs there or even recommend it just saying they will go there without danger of coil bind

Consider matching the cam to your compression ratio which will be 9.8 to 10.2 depending on the head gasket, chamber, and deck clearance. Also your tolerance for noise and smooth low speed manors and riding style.  Focus on the duration and event timing first, then lift. Works out to a cam in the high 230s or low 240s for duration, intake closing of ~38, and few of those are over .600 lift. You have a whole plethora of cams that will work well and a few that will work great off the shelf and all that I can think of are under .600 lift.
I no longer pick specific cams unless I am helping with head work and the rest of the build but this will get you started.

Thanks for the further assistance.
I'm thinking the 57 will probably stay for the time being.
The help I've received in changing the map has improved the power and the rideability.
The bottom of my wallet is easily reached and the current performance should satisfy my itch until I work out which particular cam will work best.
cheers,

ok we know you in good hands with Mac, as O4 SE Deuce asked, what was wrong with the tune

as highlighted the HP was well down, VE, Timing,? didn't the tuner have a dyno?
