ls1 to ls2
 

hello guys ,
I having problems with my ls2 swap and maybe you can clear some things up for me ,I keep getting cam dtc codes .I replaced the 4.8 in my Silverado with an ls2 .Ialso installed a 4x timing gear and a tan sensor .will this reproduce an ls1 signal?it will run but when logged with hp tuners timing is at 27 degrees even though its commanding a max of 11 (turbo'd)



thanks in advance
