Black2003ssnj Posted March 24, 2016 Report Share Posted March 24, 2016 Hey guys , I been here awhile mostly just reading what everybody does to there trucks , and this site always helps me out when I'm having problems , always find my answers pretty easy , so that being said thanks for all the help .here is my issue , I have an 03 SS with a Maggie ,2.9 pulley , after dropping a valve and screwing up one of the heads I changed to different heads a different cam , and bigger injectors , then I sent the PCM out to have it retuned , got it back and had issues with it surging when I go to stop and stalling , was told to drill a hole in the TB plate , took it to have a tune done the rite way figuring I don't wanna b drilling holes in the TB and I got it back and it still stalls and surges, think it actually runs worse now then when it was just a mail order tune , thanks in advance guys any help will b greatly appreciated Quote Link to comment Share on other sites More sharing options...

jeremybieser Posted August 17, 2016 Report Share Posted August 17, 2016 Not a mech so my word isnt gold, but i literally watched my mech today drill a hole in my TB blade with a WTF are you doing look on my face, fixed the surges though.... Not running a Maggies but i am f/i with cam, heads, blah blah blah... Hope this helps, worst case youll just need a new blade Quote Link to comment Share on other sites More sharing options...
Krambo Posted June 8, 2017 Report Share Posted June 8, 2017 If it is surging, you tune needs work. Base running airflow, throttle cracker and follower tables (provided all other inputs are correct). Drilling the throttle body is not the ideal way to address the issue when you can simply change some idle airflow numbers with a few clicks of a laptop. I have successfully tuned pretty damn large cams with zero surging or sputter without drilling. IF you absolutely need to drill (with like a sewer pipe of a cam), somewhere on here buried in one of my posts is a correlation table of a (drilled) hole size to idle airflow...may be a good reference for your tuner.

zachm89 Posted June 20, 2017 Report Share Posted June 20, 2017 Come on Krambo, you're digging this one up from the grave. A 10 month old post around here is like a 10 year old post on a higher traffic forum Regardless, good info from someone who knows what they're talking about so at least the next poor bastard who sees this thread will have something knowledgeable to read!
