A performance map from a tuning company such as SAWS or Force Tuning can get you closer to the "160" number, but it's not possible to hit with the stock turbo, you run out of boost. With a manual boost controller set to 24psi you can hit just shy of 155bhp.
Fit a bigger turbo and you will then be limited by the fuel system to around 165bhp.
I've said time and time again that a dyno run with video and printout proof should be done for this map. There is some sketchy evidence that is an excel spreadsheet showing that a car hit 170bhp with the map and a synergy box, but it is simply not possible because of the mechanical limitations.
There are a few people that have gone from a "160" map to one that maxes at around 155bhp and they have noticed a significant performance increase. I wonder how that is?

See you're still plugging your mates tuning company whilst dismissing our tunes Jamie, some things never change
Depends on the dyno and how it's set up
Everyone who knows anything about dyno's knows that you can test the same car on numerous occasions without modification and get entirely different readings. you can get it to read what you want.
Just because you've not managed to get a car mapped to 160 doesn't mean it can't be done.
Did you know about the two grades of engine fitted to the 75/ZT?
It's why some are far quicker than others and produce more bhp!
The A grade engines were supposed to be fitted to the top line cars the B grade to the lesser models (where possible). Towards the end they fitted what they had, it's a case of pot luck so you're never sure what you have fitted
There's a thread on here in the dark recesses of the forums that was commented on by someone who worked on that part of the production line who expained this.
I've encountered it many times when identical cars with no issues have been a lot quicker than others.
I remember one particularly well was whenI lent Dave (Duotone who was a mod on here) my car to get some parts for his car. He returned and immediately commented that mine was a heck of a lot quicker than his! Same spec car built within a few Vin numbers, similar mileage, serviced regularly with exactly the same readout on all systems
We've never claimed that a 160 remap will definately produce it on a particular car only that on independant Dyno's have shown that it was achieved when tested by members that had it applied.
And which 160 map were you comparing yours to, there's more than one and they're all different with slightly different output figures
We've never actively advertised the map it's always been done on the recommendation of others. We offered them as there were and still are a lot of really bad ones about people were paying good money and either ended up with a really rough map or one which failed the emissions test. All of ours cause no issues with the emissions test unlike some from the sources you mentioned
Here's an recent example of a comment of a forum member who was recommended by another member to have it done:
"Hello Russ
Thank you for the work you did on my 75 on Thursday
I had a V8 in Australia, now I feel like I have 308cu in under the the Rover bonnet. Smooth, instant power.
All the best John"
By the way TiRich's car, Hogwartz and JohnDotCom's cars were all dyno'd and produced 171bhp. Rich's car used a TU3b and John's a Synergy both on top of an Angel remaps tune.
A simple Google search will show the results and also the you tube link to the 162.8 run on another Rich's Auto.
Unfortunately due to Photobuckets greed a lot of the other dyno result photos on here have disappeared and as the members concerned have moved on it's not been possible to get them to resubmit them.
as you well know
Russ
