Got my VY SS Series I run up on the dyno today.. 3 runs..
Im running mafless tune, otr cai and cat back 2.5 inch twin redback exhaust.. stock headers and cats... mines a manual too with 113,500k's on the clock
on the first run she pulled
277.8 rwhp
Second run pulled
280.5 rwhp and we noticed a nice hole in the timing map.. we temp adjusted that hole to make it straighter and netted
291.5rwhp, now from the graph/printout, i can see the tuner who did mine needs to adjust the tune somewhat in the 3000 - 4500 rpm range.. which should net me just over 300rwhp after being done..
Also want to get some pacemakers and hi flow cats done which should give me another small increase.. maybe 10rwhp..
so yeah more tuning to come for me!
oh and rough conversion of 291.5rwhp is 217.5 rwkw's
