Thanks Doood. Close thread.

 

all you will get from phearable is a basemap. basemaps are a rough estimate of what your engine may need based on similar setups. they are used to get the engine running so you can get it to a tuner.

you should ALWAYS tune when increasing compression like that. you cant tune without an EMS like hondata or neptune.

 

K that takes care of that question. I just wasn't sure since I see/hear lots of people running LS Vtec with a chipped P28. Thanks for the quick reply. So now just the answer on if those CR seem accurate or not.

 

they're rough numbers. only way to know for sure is take your own measurements and do some math after everything is said and done.

 

Alright thanks. That gives me an idea.
