Boost probs.
Well. I just got a new DP cause my PreCat probobly was bad, I then had big boostspikes at first turbo and 6psi of boost at high rpm.
Now it goes much better, it still spikes the boost when pushing throttle fast so I have to go easy on the throttle, How can I get those spikes to disapear?
Second thing is that I sometimes have a nice 10 PSI on second turbo, but sometimes it just gives me a poor 4-5 psi. What can that be?
Thanks.

one fault was the popped of hose at the tank. I have also made a DP, a CB, intake mods and the pettit ecu.
Then I have changed the pills so now I use 12 psi at primary and 10 psi at secondary with no boostspikes at all. I am very satisfied with my car and it goes vey well.
Yesterday I raced a RX-7 that was mapped on the dyno with so called "unichip" boxes that work together with the stock ECU, it boosted 15psi@285Hp and I beat him quite easy on the straight of the track.
So I have really understood the meaning of tuning the rx-7, tune it properly at intake and exhaust before turning up the boost. I am a fan of reliable turbocars with modern boostpressure, sure High boost is fun but I dont want to use it on my car on the street.
