Question about tuning - 3800 NA motor (Page 1/1) qwikgta APR 20, 02:08 PM I've been daily driving my 88 GT w/ a NA 3800 for about two years and I love it but was looking for some more power. I have a set of TOG headers and was thinking about upgrading to a 3800 SC motor Throttle Body. I have the stock NA TB on it now. If I do, will I need anything done in the Tuning? Will the different TB and headers cause an issue with the tune it has right now? Thanks in advance.

Pretty cheap to find everything you need these days. qwikgta APR 21, 10:47 PM quote Originally posted by OntarioKev: It will likely run on the factory tune without issue, but to maximize the gains a tune would be best.

Just want to know if the car will run w/ the headers/TB on the current tune so I can still drive it. The LS4 is going to take a while, i'm still gathering parts.
