I have a JWT which claims approx 12bhp gains, I shall be fitting a Motordyne spacer very shortly which I think claims approx 12bhp, and I'm ordering an exhaust system this week that should give another 15bhp, claimed.
So with all of these on, and after my learning ecu has been tricked/re-mapped into accepting these popular mods, ( at RS Tuning as they are only an hour away ) shouldn't my car end up being somewhere near the 320bhp+ region???? I notice Nurrish only got to (a respectable) 301bhp, and would have expected more?
Would these higher figures be possible with a piggy back, or are the claimed figures just marketing?
