I have an ITR that has a modified N/A build motor. It has the following mods:

12.5:1 Pistons bored over .5mm
Skunk 2 Stage II cams
Skunk 2 valve springs
Larger Injectors
Aftermarket Fuel Rail + FPR
Aftermarket Fuel Pump
Apexi V-AFC

The ECU that came in the car is a 37820-P28-A02 that is socketed, it was supposedly tuned by Phearable a while back. When driving it, the redline comes in at around 7k, well short of the 8400 redline of the ITR. That said, I don't trust the tune that is on it.

Two questions:
1) How can I read the ECU to see what tune is on it?
2) I have a stock '98 ITR ECU, is it bad to plug it in and use it, I would assume you wouldn't get the best performance for the mods, but is it bad for the engine? Maybe it would run rich given the larger injectors and fuel system?

After doing some drives I notice that it indeed does NOT have a 7k redline, it is able to go above it when not WOT. When at WOT it feels like a bogging that will not go above the ~7k mark. After speaking to the folks at Phearable, they think it has the stock 240cc injectors. Can that cause the issue I have? Or will smaller injectors just lean out the A/F?

Anyone or any tuners in the northern Maryland area that can diagnose/tune old school ITRs?
