Hi,
I thought I would post my experience today with a call to a dyno tuner.
I asked how much for a dyno tune and he said $1100. I asked if that is a mafless tune and he said yes and then he asked why a mafless tune specifically. I said well you get more power and he said its not much in it only about 5kw.
So I thought does this guy know what he is doing with the LSX motor tuning. He uses vcm tune not EfiLive and I just wasnt convinced.
He said that regardless of what you read on the net, the tune with a maf is better because you get better fuel economy and its only a difference of 5kw.
It makes sense to me about the screen in the maf being a restriction and the slight delay int he maf signal getting to the PCM but I mean it sounded more like he didnt know how to mafless tune.
I have read the pros and cons between the two and I must say in alot of the jappas they never go for a map sensor they always get great results from a maf tune.
Is it possibly just a bug to bear for the Holden OBDII Pcm?
Thoughts?
Cheers.
