Hey,
1) Forge only offer that 130 bhp intercooler as you having a 150 will have a front mount IC. You could try the uprated SFS pipework.
2) Your system N75 valve does a better job than a boost controller can. Not sure your car will ring right with the request and actual boost being different. May be wrong.
3) Hybrid is good, CR Turbo or the likes can do.
