RX7 FD redom type B ECU

Hi all,

I've had my 1993 rx7 FD off the road for 4 years now, had it in pieces over that time, moved lockups 3 times and converted to simplified sequencial.

My problem is before all this my car would boost to 1Bar on the second turbo. I believe this is because I have redom type B ECU which says 1 bar written on it.
Now, after 4 years and lots of changed and work on it, it only boosts to 0.5bar primary then 0.7bar secondary. There's no issues at all, in fact it runs really well if it was suppose to be stock boost.

Any ideas why it isn't running the ECU boosts?

Cheers
Jay

Probably have a boost leak for that much of a drop in boost. Look for torn, loose, or cracked couplers. Tons of info on boost leaks and common places to look.

or the boost control isn't hooked up correctly.
