If I ease into the throttle it will let the sled go past the stock limiter and work fine. If I stab the throttle it will hit the limiter wherever I set the rpm takeover which is odd. It worked fine before I added the turbo and I have another stock sled that it works fine on all the time. I only added the turbo late in the year so I didn't have too much time to test. I will keep testing this winter.
Are you using the pcv pti?

Yes, sled runs great otherwise

Are you using a stutter at all? If so how is that working?

Are u getting it to build and boost when it's on stutter? Or is it just zero or vacuum?

Great that's good to hear, I have the pcv pti and ignition module waiting to go on and doing the stutter too, just gotta wait til it gets colder to get it on the dyno and tune it.

I want it for the rev limiter increase so I can clutch the sled better and utilize launch control.

Its alot easier to build boost on pump gas in the winter with the stutter but without timing control while on the button it is harder to control

Do you mean around 8800 ?? where it "grabs" the signal??

Yes, but I can change the takeover rpm and the limiter seems to change with it. It's odd because it works fine on the stock sled.

I had the same problem with my turbo apex last year, I tried pcv, pciii and rev xtend wouldnt work. I have both working on my stock sled, and I changed ecu, harness and everything and still wouldn't work on the turbo, put it all back to my stock sled and it worked fine.

Is it only the pcv PTI version that making problems with boost and rev limit , and no problem with only pcv/ign module with higher rev?
