Graham,
My planned mods were a 2.55 upper, cai, LT headers,no cats, and a cam like an ls9 or similar.
With a tune, how much rwhp should I expect on 93 octane? race fuel?
Do I need a fuel pump or injectors?
Is it possible to send you my ecm for tuning, and how much is a tune?
Considering the boost drop from the LT's should I consider a 2.38 pulley instead?
Thanks, Mark
