Default runs horrible after cam install...

i just finished my tr224 swap to a t-rex advanced +2 with hand ported stock heads.. and i took and plugged the EGR off real good. its loading and back firing when comming from mid rpms back down to idle. and feels like it has no power whatsoever when WOT

my question is is this normal. i mean my car ran kinda crappy when i went from stock to the 224/ but this is worse. think a tune would clear all of this up?

opinions please!!!

Wait a minute.... your ran your car with a tr224 without a tune for a while? how was it?

Im amazed you got that to run .... let alone a TREX, jeez. I though i would have get a trailer to take it to a shop to tune it after a tr224 install.

I'm running my 224 cam & added some heads without a tune. Been driving it everyday for about 3 months. Gas mileage even stayed the same & no SES light. Thats a reason the 224 cam was so popular back when the LS1 first came out. You could install it & it will drive on a stock tune.

To the O.P., I don't see a converter in your sig. Are you still on the stocker?? Cause if so your car really isn't gonna be happy when you get on the dyno with that big *** cam & a stock stall. And yea, a T-rex without a tune isn't gonna run that great to begin with. It's definetly a cam that needs tuning to drive around safely.

That is only true in a six speed car. An auto needs a stall and tuning to be right.

You should change your oil before you do a dyno run, check your plugs too.

Definately do your best to put a few miles on the car and change the oil. Cam bearing shavings in your engine at high rpms just is not good.
