πŸ”₯ We got Robert’s 57 Bel Air ready to go out to the exhaust shop now and then we can finally finish up the tuning on this nasty built 6.0L engine! πŸ”₯

We had to diagnose several issues , and properly repair / adjust his front suspension from a previous sub par installation to get it road worth again. Now to fix the massive exhaust leaks and we can get some data and make some pulls!

Remember everyone we don’t just tune, we BUILD what we tune. Professional installation , the right way, the only way.

❗️ This ain’t your average Jeep here! ❗️

Andrew contacted us for some drivability , and startup issue so we had to get him dialed in! Shoot of some fuel pressure issues towards the end of our tuning which will be corrected , this things a totally different beast! We also confirmed and set his static timing for him since whoever installed it had it 8* of timing advanced from what it was base set at. Yes , you read that correctly, we actually ( unlike a lot of β€œtuners” ) know how to use a timing light πŸ˜…πŸ’ͺ🏻
