hard time tuning 272/278 cams
Posted: March 15th, 2025, 11:55 pm
Alright I've been tunning Mazdaspeeds for a few years now and being very successful, most builds have been typical full bolt ons, built bottom end some CS cams, done big turbos and aux fueling. most tuning range from stock to about 525 nothing higher since the average person dont have the mods to go higher but lots of FBO stock fueling.
my build its pretty much fully build ill get a list together but being having a bit of a hard time close loop finding the timing cams like, stock tables dont help, its been liking alot more timing bottom end but barely anything top end compare to other tunes and in between just having a hard time in general making it happy.
anyone have a table similar with this cams, since we can only flash is a bit impossible finding true Ignition MBT for close loop area cruising driving...feels sluggish and anything above 4k goes crazy acceleration aggressively just wants it all fi you know what i mean.
also vvt at 0 since not sure my limits there with this cams
also idle sometimes likes it sometimes it surges
wiseco pistons 88
h beams
625 headstuds
arp bottom studs
fully balance n blue print rotating assembly including clutch
key crank
top mount 5858
hood exit
P&P head 5 angle , behive springs, kelford c2 272/278 all the goodies
W16 intake mani, 72mm throttle, 4 inch fmic, exteral oil cooler
2200cc 8 port
e50 main tank full e85 on fuel cell that feeds top injectors
....thats the main stufff and of course all the lil things to support it.
