Update
Plot below is prior mods v latest intake mods with stock EWG turbo and Shell v power fuel ~ 98 RON
Prior mods green lines from same dyno in 2015:-
Map 6 Jb4 ewg board + harness and FF wires
BCS sport cat DP
MPE
Oem air box with Afe dry drop in and afe airscoop
Latest mods red lines recently:-
As above but with intake mods as follows
Map 6 - minor fettling co BW Chiptune.
Dinan CAI with afe air scoop
Wagner evo 2 comp FMIC
ER boost pipes both sides of FMIC
Pure hi flo inlet pipe
Peak gains may look marginal but "area under the curve" is much improved.
Deltas more evident from mid range upwards and Jason @ BW Chiptune drove the car after he'd fettled it and was v complimentary about how smooth the car felt. This is evident as red line is smoother than green line across the full rev range.
I've yet to drive the car properly so too early to comment but what I've noticed initially is that Dinan CAI has more "voice" in a good way with Pure hi flo inlet pipe.....
Hats off to the guys at BW - great service and advice as usual.
