Hey Zilvians, I would like to know who is using a large turbo (above a 30r) with a rom tune such as JWT or Enthalpy. Share your results and troubles.

I have a forged short block with a factory head and a Precision billet 5858 mated to a Hybrid Dynamics manifold. I plan on using a friend to tune the engine eventually using Nistune or AEM, but I ran across a JWT ecu tuned for (and including) a lightning maf and MSD 96lb injectors for dirt cheap. I plan on running with it for the time being until my build progresses to the next level.

There is hardly any info of people using rom tunes with larger turbos. It seems that the fwd bunch tends to go this route more than we do and they seem to have descent results.

My biggest question is knowing how far to go with boost. There isn't a way for me to monitor knock that I know of and the A/F ratio is only so good for monitoring the tune.If anyone has experience with this chime in.
