[quote=“neonglh,post:137,topic:37965"”] Even then though, the head just flows so much more air then that turbo can, its impossible to stop the taper. We did some experimenting and got it to stick a little bit better. I ran 29+ degrees of timing after torque peak. By adding more timing, I was able to pick up some power that fell, from the boost falling. We also ran an AGP wastegate, which combined with a really nice boost controller, only tapered to around 18 psi, down from 34. Using the stock wastegate, no matter how much boost I ran, it would always taper to under 15. –mark [/quote] the srt should have had a 50 trim from the factory. 🙂 the stock old school td turbo is bigger… but the cyl head is garbage. 🙂 i have to shift at 5k Brian --- _[View the full topic](https://forums.speedlife.net/t/crx-stage-2-srt4/37965)._
