Jb4 newbie, map 1 vs map 5 interesting

Hi Gents,

I'Ve recently fitted the following bits to my n55 135 dct, jb4 Stage 2, AA sport cooler, BMS CAI, BMS DECAT DP. I haven't ordered my USB cable yet... I was under the impression it would come with the JB4.

We have the equivalent to US 91 oct fuel.

I started on map 1 and the car felt good, I saw approx 12 psi on the dash gauges.

I then tried map 5, I did a few WOT RUNS and WOW WHAT A DIFFERENC!!!
I now see 15 plus psi and the the car feels AWESOME.

My question is I how safe am I on map 5 as I can't "log" and send info to the master Terry.

Thanks in advance.

Map 5 is recommended and you should be fine using it. Why don't you use map 2? You have all the downpipes and intercooler?

Yeah miro2296 my friend has the exact same mods and he keen to try map 2 with NF OCTANE booster but I'm not that confident...

Ive also still have to fit my meth kit... That should ensure things stay under control...

Pretty sure you should be fine with map5. Makes me wonder what types of gains I'll get switching from map1 to map5 without a DP

You're still gonna see about 15psi without dp. But with dp you just get the little extra umph and faster spool. So fast that I it breaks traction in 2nd gear from a roll

....and faster evacuation of exhaust gasses and lower EGTs....which effectively increases your octane (in theory) by helping to minimize cylinder temps and knock thus allowing for more timing/power for longer periods of time.
