    5.3 bore to 5.7 LS Engine

    Hello, I am teaching myself how to use HP tuners, I have a 5.3 engine bored to 5.7 and I want to know where to start to turn this little bastard on.

    What parameters do you change? or some tips that lead me to the goal ----- A STABLE DRIVE WHILE THE CYLINDERS ARE POLISHED.

    This IRON 5.7 has a 230/241 .625/.605 113 LSA camshaft with 243 heads, approximately CR:10.6:0

    I WILL BE ATTENTIVE TO YOUR ANSWERS

    Thanks for his help.

    Do you have any tuning experience? That's a big cam in my book to start tuning on, just saying.
