so my factory ecu is in
 

the dealership changed it back to my factory one.........


and i am spiking at 15 setteling at 10.......

my boost guage could be off a smidge, but that much?



i have a race valve fmic tp and 2.5 in exhaust, should that make me spike that high?

RE: so my factory ecu is in
 

If you have stock programming you should be running 7 PSI boost. Higher peak is due to the N75. Sounds like your boost gauge is optimistic by 3 psi

or just junk, like i think it is
