Thank you Anythony.
ZO6 Eric.
Thank you for staying neutral. I did not make this post to say I was a better at tuning then a competitor. I made about 5 different flashes to the truck to get the fuel trims in line. I agree the gm maf is accurate for the most part. I am not sure how both the cold intake and the E10 fuel played a part in my having to modify the tune to get the trims in line.
Fact of the matter is this.
There are some people that prefer Dyno Tune, others Eric at IPS, and the Lasotas. Go to the place you are most comfortable with and stay with them. I am sure I have old customers that go to both Lasota and Eric because they were not happy how I handled things. I can promise you I get the same thing in my shop.
We can not make everyone happy. All we can do is try.
