I know your car and your map, your map is decent. The dyno is a strict one so 223bhp wont sound much but it would dyno more if you took it else where.
I respect Courtney they are good and done very good work on my car but I dyno there and the following day dyno at where your car was mapped (you got Adam's car?) and lost 20 BHP. Obviously I didn't but each rolling road has different figures. Rich's Dyno is known to be accurate and doesn't throw out happy figures. Always read a bit stricter than most.
If you want more power you need a 80mm MAF and bigger injectors (VXR) as your std injectors and 70mm will hold you back. I had your same MAP in fact your orgfinal map was mine then edited for that exact car as Adam used the same tuner after me.That will help a bit as the duty cycle was nearly maxed and MAF was pulling 5v all the time but really heat is the issue. A CC or meth is the only way to get some good power but then you will need a clutch and VXR turbo.
I tried all sorts of things on the dyno day regarding high inlet temps. The only real answer is meth or CC. I tried the bigger intercooler and it helps but still hits 70C+ with CC or meth you will have sub 50 and 40C on a cold day
You wont get much over 290/300bhp on a 2.5" system hence CS recommend the 3" version as they will pump loads past the 300BHP with ease
