Coming from the bikeing world BHP figures are all much of a muchness. It's best not to compare to others unless run on the same dyno on the same day. Even the same dyno on the same day and same vehicle can produce different results as atmospher plays a big part too the afternoon being cooler than the morning etc.
All dyno's read differently to eachother and also different makes of dyno's use different algorithms to obtain the final figure. Best to compare before and after and then if you are happy with the changes after. Looking forward to seeing what mine makes before and after remap.
