adding only boost....Dinan Sport tuner
Hey guys,
I was hoping one of you more knowledgeable car enthusiasts could enlighten me.
I have a f30 335i PWG. i had a JB4, but sold it. wasn't consistent. would drop power sometimes completely at 5-6K, etc.
it was a lot of power and this may sound lame, but i don't know if i want that much torque. i live in a busy city with a lot of traffic, only have a mile commute, just not practical for me.
so i'm looking at the dinan sport tuner that just came out.
it looks like it just increases boost level up to +4psi over stock.
is it ok do add up to 4psi on our engines without any timing modifications, etc.? could this be harmful only adding boost and no other variables or does 4psi max not seem that harmful?
i ran map 1 on my jb4 and i think that is only 4psi over stock, but my understanding was that the jb4 had many other variables to compensate the additional boost.
would love some insight from some smarter people. thanks guys!
i was also looking at the mppk, if you had thoughts on that over dinan sport, i would love the input
