I'm sure Tony knows the difference between a RRFPR and a plain jane 1:1 like the Aeromotive models, etc. Definitely get your A/F ratio out of the tens. That'll really slow you down. Likewise, get the leaks around the injectors fixed or you'll have tune/spool issues as well.
For leak testing, here is what I do. Find a piece of pipe that fits into the coupler hooked up to the inlet of your turbo. Weld a plate across one end of it to seal it off. Drill a hole in the plate and weld a compressed air fitting onto it that fits your air system. Hook up a REGULATED compressed air line that has been turned down to zero. Slowly turn it up to about 1.5X your estimated highest boost pressure. You want to go higher than your boost pressure to try to help simulate heat on the couplers and the surge of force as the turbo spools. Leave the throttle alone. Don't install any blockoff plates, etc. You'll notice a bit of hissing if there's any overlap in the cams and you hit the right spot in the timing. Otherwise, move your ear around everywhere really close to the engine and piping, etc. This should root out any leaks. Be ready; if the couplers aren't tight enough, they will blow off and when they do, it's pretty @$#@ loud.
