The big spray pattern ones will support them but are a bit heavy low down on light throttle and some make more power than others!!
As said a set of 83lbers is your best bet,just sell the greys and get the siemens ..job done..

The only problem with a road map is you never know if youve got the best from the engine ie tractive effort or roll over so its a lot of guess work..
Theres no power to work with and or known so can only go to the dge of det and back...
Not slating thier mapping but just cant see how you can get the best from mapping on the road but im sure loads of people will disagree and now say im talking shit!!lol????

personally i think its a very tricky debait. on the rollers you can make comparable runs and see gains / losses which is great but it still isnt being used on the road ie wind resistance and load on drive wheels cannot be the same on the rollers as it is out on the road.
my gtr was mapped on rollers and could only run 1.2 bar at 90% inj duty 11.4 afr, map was checked by another tuner on the road and it was upped to 1.4 bar and its still 11.4 afr 90% inj duty ? admitedly i dont know what duty and afr the rr map was on the road i didnt look but in that situation road mapping yielded better results, it is noticably faster

It wasnt mapped to its full potential on the rr and imo it all depends on the rr as on our old maha i can honestly say it was no better than a road map but on the dd rr its so much better and easier to replicate certain road types but with tractive effort you can actually take it to the best optimum roll over point and on the road you would never know that...
Imo your car could be even better but obviously youl never know unless you try..id be willing to give you a free run on our dd to prove a point???
Theres load points on the dd rr that youl probably never experience on the road and when checked on them loads you go through all the different break points of the map for det and then do a final check out on the road...

Imo id say youve got a noticable gain in power by just taking some fuel out and still be well safe!!!this would also safe some injector duty witch would help???

i see what your saying though mate as my old saph was mapped to 11.4 but that was running 2.2 bar t4 ! could it run safe at 12 afr then do you think on 1.4 bar on twin gt28s and there 660 cc injectors.
i suppose i can do what i like to it now as its been almost a year and over 3k miles so my bit of engine warranty / cover will have expired now.

I think youve answered your own question there...

11.4 at wot is what the engine builder wanted it mapped at mate. rr map was done on a fairly new dd. cruise is 15.5 afr and is smoother than smooth everywhere
i see what your saying though mate as my old saph was mapped to 11.4 but that was running 2.2 bar t4 ! could it run safe at 12 afr then do you think on 1.4 bar on twin gt28s and there 660 cc injectors.
