Well, chris n nic had his Superchipped and it only gave him a 3bhp gain, so he had it removed and now runs the R-Sport ECU.
His car runs the 1/4 mile in 14.1secs @ 98mph now! ;)
I was gonna get the RR operator to try this with mine on Saturday and see if it makes any difference at all...
Do a stage 1 then stage 2 (with click) run and see if the power/torque curves are different.
That will settle it once & for all. ;)
Good news... I was gonna recommend the JBL GTO-525/526es that myself & others have got and are very pleased with!

A snip at £30 a pair!
So what if several 172s & Cups are all tested on the same rolling road on the same day and they all varied, some by quite a bit?!
Becuase this has happened in the past... at RE in fact...
Go on... what you get in the end?!
Yeah, I got an e-mail off confused.com telling me theyve added the Cup, so Im responsible for sorting that out! :D
Awaiting quotes as we speak (type) actually... ;)
Would like to see what your @ wheels figure was from PE.
As for the Northampton one, the give you a 17% loss which is a little high, but not as OTT as some Ive seen which are way out.
Keeping that loss as a constant, means you would have 139bhp @ wheels from PE.
I reckon a spot on...
AS has already been said, there will be a few of us going on the rollers this Saturday, so we should have a load of actual figures soon.
Its not 172bhp as we know it though, its 172ps or bhp/DIN which equates to ~169bhp in what we in the UK call "bhp" and should be about 143bhp @ wheels...
