i have the comp XE 224/230 cam .503/.510 lift on 112 LSA i am currently running the stock computer tuning, my question is will i benefit greatly from a tune and an LT4 KM, in other words will i see significant power gains? i think with the LT's and my loud *** exhaust i am getting some retard without the LT4 KM. thanks in advance.

The cam is a major change. You should get a tune any time that is done. The LT4 KM couldn't hurt, but you don't know if you are getting knock retard (or false retard) unless you check it with a scanner.

 

thank you
