i have the Utec and I had a stock block. Building a shortblock now with compression ratio of 8.8:1. Wondering how much difference the tune will be? Like how bad will it run with that much of a change? I know i will need a return and will get that but will it be safe to drive it to lets say Sharifs place? I live in NC so roughly guessing 6 hr drive maybe less

 

get multiple maps made. get a basic tune along w/ those. get a low boost/street setup, high boost/street, and a high boost/race setup 4 the track.
