Message I have a heavily modded 300ZXTT and had a tune years ago from SZ, but My Z has never ran properly since. I did not get a full tune because after the 2nd pull, my front oil seal busted. I paid for a full tune, but never got over 4000 RPM's. I had a Z1 generic tune B4 with Ebay turbos and a single intake with much better results. Now I have:
90mm Weisco Pistons
JWT550BB turbos
Nismo 615cc injectors
Selen translator
JWT dual intakes
Z1 larger throttle bodies and plenum matched
Z1 flywheel
Southbend clutch
inland empire Alum drive shaft
All new suspension
Billet motor mounts
All new wiring
All deletes done
SZ 3" downpipes
SZ pipes to the back. No cats
Blitz EBC
HICAS delete
Stock heads and exhaust manifold
I run 95 octane with toluene

My Z used to rip pavement up, but now it is slower after adding many upgrades, intake and tune. It also knocks at 3000 rpms in all gears ever since my tune. I never drive my Z anymore because it feels so weak now. The engine has only 7000 miles and great compression and no leaks of any kind. My Conzult shows no problems.

I can't drive all the way to LA again. No time and don't want to go through all this again.

Do any of you have a suggestion? Buy another generic dual intake chip? I'm not spending much more on my Z. I don't know who to trust. If you know someone in AZ that is a good tuner, please let me know. I have spent many years on this car and it should run much better. I don't want to take chances. I would greatly appreciate any suggestions.
