Hey folks. I have a P1 with some mods. Was mapped to 1.4 on defi, with 1.5peak sometimes but dropping off after a sec, by Andy F (was told defis normally 0.1 higher for safety) anyway, noticed for last few days its getting quick peaks of 1.6 and settling 1.5. I'm wondering if the ecu can adjust the boost higher for fuel quality,as i'm now using v-power,or something like that. or whether theres something wrong with a valve or the control side?Was mapped with safety margine as Andy norm does if wanted.
cheers Brian
