I must be stupid tonight. I re-read this 3x! If this is a stock Comptech kit with the Comptech supplied FPR, what exactly are you going to have tuned? There's no need unless the kit is used and the FPR has been altered or adjusted in some way.

Since the stock kit relies entirely an ESM to mask boost and a FPR to push more fuel, the only adjustment available is more or less fuel pressure.

If I'm not understanding and you aren't going with a fuel delivery setup that is standard for the kit, I would not run the belt. Why "guess" at what fuel pressure should be for 300 miles? When I was at stock boost, fuel pressure at the rail varied from 35-40psi at idle to easily over 80psi at rpm. Again, if this isn't a standard kit in some way, then install it, drive and hope for the best seems like a bad idea....if it is a standard kit the trip to the tuner is optional. Not a bad idea for a double check of A/F's but not necessary.
