Well at idle it was very irregular and was constantly hunting up and down and when you tried to rev or accelerate it was very slow! I got it from Soler performance throttle bodies and the guy has been super cool but he said he's not sure what I could do either!

I actually did change that to a 4" id from factory which is 3"ish if I remember correctly including where the MAF is located and the shop said they corrected for that while tuning for the cam, lt4 fuel system smaller pulley!

Hey just a quick question! I have a 5.3 with a whipple 2.9 and I have tried two ported lt5 throttle bodies and both will not work correctly so I'm running my stock throttle body still unfortunately but still made 550whp! Any tips on how you made yours work, anything special while tuning? Thanks!
