As above when acceerating through the rev range i hit around 5k & just a sudden loss of power i also notcied later on a smaller loss of power lower down at around 4k. I ve recently had new coil packs & plugs changed so i cant see how it can possibly be them. My engine light came on at one stage & was flashing then went off !
I have a forge 007dv fitted & BMC panel filter no other mods, its due a service to & is booked in with with JBS for friday, i just hope they have the parts required if any are needed prior to re-mapping or its gonna cause problems.
Any help would be good.
