Main reason it was pinging he said was because the timing was so advanced, but the chip was tuned for 98 and i can only get 95 here but maybe that wasn't the reason. Either way he retuned it to 300hp at the wheels no pinging and iv now gone from 96% duty cycle to 86% duty cycle. which is fantastic lol i've got just the power iv wanted he has fixed the pinging that i never knew it did :/ and the duty cycle is way down.
Here are the graphs for whoever wants to see.
My mods are: single Apexi intake, stock jdm down pipes 3" test pipes 2.5" rear half H pipe exhaust system, 14psi boost. (my gauge lies and says 13 then drops to 12).
