Arrow Greddy Turbo

Ok first problem, when I put the kit on at the beginning of summer. I had trouble with the boost tapering off towards redline.

Did a bunch of tests found out the manifold just needs to be tightened.. Problem fixed.

Next problem:
When getting on it the boost builds like a supercharger going from 7-10psi it felt fast and fun but not right. Drove it the next day now the boost stays at like 7psi but holds all the way through but i can't turn the boost up. I have an AEM Tru boost. For me 30-35% duty cycle is 10psi. I did turn it all the way up to 50% duty cycle and it hit 9psi then drops back down to 7ish psi and holds to redline. Do I need to check again for a boost leak or something? Sorry new o this stuff and its all ready pissing me off.

I really need some input on this and hopefully I can find out whats wrong.

Not sure if this a greddy question on a boost controller question. Weather does make the car feel way different but seems like the car is running off the WG and needs more gain

Sorry guys im a dumbass we switched the solonoid tubes around for some reason and I just switched them back bc port 2 goes into the wastegate and I had it switched around. Im at 45% and at around 9psi now.

Yeah I think the main problem was the manifold needed to be tightened and tubes switched around. Thanks for the input guys never fails for help on this site.
