Ive just wired up my mechanical Prosport gauge. The whole reason I bought it was for a cheap gauge that looked the part. Think it cost me like £30 new. Its smoked, lights up green or white (you can buy different variations) Ive mounted mine on an replica apexi mount, cost me like £5 and looks the biz. Im currently running stock boost (0.65 bar as far as im aware) and the gauge reads 9.5 psi on full boost so to me seems accurate enough for my needs (boost was creepin in the frosty weather and fuel cutting in 4th @5000 rpm just wanted to know how much). Ive had no other experience of other gauge
