went to the dyno today to get my boost increased and at the same boost level of 13 psi car has lost 43 rwk
8 weeks ago my r33 gtst had 220.6 on 13 psi and now 177.
turbo is only 2500k's old, new clutch installed. nothing different.
tuner still hasnt done a compression check on it but he said the engine sounds very healthy.
there was no misfires on the dyno run or milky substances in the oil.
another thing that got me concerned is that the a/f ration were tuned at 12/1 and now they had gone up to 13/1.
rob put them back to 12/1 but no increase in power was made.
this is a huge power loss and i dont know where to begin.
mod list is here and nothing has changed
r33 gtst with
pfc, blitz fmic, 600cc hiflowed injectors, tomei fuel pump (intank), mtq hiflow turbo, z32 afm, panel filter in stock airbox.
3in turbo back exhaust with hiflow cat
need some expert advice
thankyou
