Lets see.. I'm having an issue.. I have a l32 swap into an 03 monte ss.. Mids: headers 3.4 pulley 180tstat tuned by intense 42lbs injectors... 1.8 rockers no cat..... The take off is slow as piss water but top end is strong.... It won't crack a tire....which is weird stock gtps can burn 18s...soo.. Ideas?
 


Possible sc belt slip? Did you get a smaller belt? Did you get a mail in tune from Intense or a dyno tune?
 


if you have sorta good tires i would expect this.. headers kill tons of power under the curve and you really are not doing much in terms of mods outside of a 3.4 pulley, which isnt much.
 


Are you seeing any knock with the 3.4??

headers do move the powerband up some, but you should still be putting enough torque down to spin the tires a bit.
 
No k.r with.4 on and I can get some chirping while turning but as far as gunning nothing.... even building up around 2500 rpm it seems to boggsit feels like something holding car back until it finally reace 3k then clears up and hauls ass... only in 1st gear
 
New filter and fluid along with lucas in trans............ tb cleaned and working new plugs wires air and fuel filters and air filters..... also when in park/nutural it revs clean when engine under load it seems to be held back
