hey i have a kenji chipped p28 with a b16a map with i\h\e if i find a tuner thats tunes crome or neptune do i need anything else or am i set with just the chipped p28??? thanks for the help sorry im a noob to the ecu tuning world

 

You're set with the chipped P28 as long as all you have is bolt-ons (I/H/E).

 

well the basemap like all of them is way to rich. if i was to add cams i would have to have another chipped made or what???

 

Reburn the old one if it's a re-writable.
But yeah, you can't just take a pre made chip for another car, and match up your mods to the ones in that car and expect it to run the same. Every car is different.
