Oh and dyno 10bhp happy? Funny enough had a car in that was mapped by a very well known person elsewhere very recently that was running a bit poorly with GM, RBC, Tegiwa manifold and good catback as well as a set of JDM cams. He said they made 257 at peak when he had finished.
I stuck it on the dyno and it made 239. Hit 245 after remap. Certainly no 257 though.
Also had a B-Series Turbo setup built and mapped by a company in Sheffield and owner had a sheet saying over 270bhp. It hit 230 on ours. Certainly couldn't tamper with the map as its chrome and we don't touch that stuff and no variables on our dyno to adjust, it just reads what it reads and is very repeatable which is the main thing.
Different dyno's read differently and can't really be compared unless same type. Only people that have the same setup as us in the UK that I know of are Owen Developments, and Regal Tuning. These actually measures on the run up and run down. Big heavy rollers that are electronically load controlled. Get one of the small lightweight ones like a Dyno Dynamics that only measures on the run up then gives outputs based on a whole bunch of variables and user input correction factors and its going to be different even between dyno's of the same type.
Sounds about right. I had my Integra Turbo setup and mapped by 'a company' in Sheffield on Chrome and it was truly awful. Partly due to it being road mapped only. Luckily people who know what they are doing with proper equipment also reside near Sheffield like Will @ RDT.
I'm going to inherit an EP3 that you guys have tuned previously with a K100 (RBC, Manifold, Exhaust, Decat, typical breathing mods) however as the Exhaust is too loud for me, do you offer tweaking of existing maps from previous customers if I were to change the exhaust to something less intrusive, give it a service and bring it over to you for a dyno tweaking session? If so I will PM or call you during the week to get a price.
I don't care about figures. I just want accurate and optimised ignition timing and fueling done by respected companies.
