its OK, but 1st here by us, 2000kms away from you almost no one can re-calibrate the standard ECU for the 3" AFM - has no the software for that to do, and mostly they even also can't remap the PGT's Bosch ECU, or they says: too old, too exotic, too...
i have never ever heard from anyone, even just remapping our ECU here on RR like you do it in the last 8-8.5 years as far i have my GT3 here
here the mappers give just a copie from a file for 250GBP price, not mapped directly for your actual car, so the SEBs are cheap(!!!) for us
its huge difference
and what a map you get for 250 for your car? starts badly, engine is just for the 2nd-3rd cranking fired up, has huge CO... bastards
