V6 kit on a ls1
The N20 works great and hits hard till u get 2 bout 4grand then it starts breaking up he has changed the fuel filter,spark plugs to a colder ngk ,and has tried changing the pills around .
I told him to take some timing out with the tuner but he keeps saying that these cars will adjust for the N20 maybe if I get some info I will print it out and show him what y"all guys think
He started off with a 100 but now he has a 75 in there should he take the performance tune and just back off the timing or richin the fuel up or both
Thank You
