Where did you get the boost controller? What did you pay for it? I need something better than my profecB. If I set it for 17.5psi in third, I only get about 15 or 16 in first and second. It also tends to creep which is reflected in my dyno graph.

Amazing times. You're race gas time is almost equal to my fastest pump gas time and I have an intercooler and ported head. I think your choice to go with the miata-weight hardtop was genius. Now my full leather and power isn't so cool I'm jealous! Oh well, I can always get a gen2 and be just as fast

If your boost is creeping then its either...

A: your wastegate
B: possibly a gain setting on the profec (also would cause not enough in certain gears.
C: Engine just dosent have enough load in 1st and 2nd to push the T3/T4 to the same PSI with the same gain...


My Z I always set the boost in 4th gear, and it'd never make full boost in first and barely in 2nd (14psi).

Ive just never seen a profec thats failed.. Maybe try a spec II? I wouldnt trust my car to anything but a profecB product (I or II)
