Yep, that's true, lol.
There's loads of things that effect a RR read out.
Loads.
RR's are tuning tools that just give measurable figures when comparing pull results.
You could put an OEM 370Z on one and set it up so that the readout says 400hp if you like.
Well I didn't know that!!!
On that Note!!
For sale OEM 350z for sale £150000 or very nearest offer,
1 million BHP with RR Printout to prove lmao :-D
