I recently purchased a pray ported lt5 TB from a forum member. I knew it would require a tune but I had read several members that ran a ported TB for a while before getting their tune without issue. When I installed though I got the p2101 reduced engine power, which immediately cleared up after putting the stock TB back on. My question is has anyone else ran into this issue just because the ecu isn’t happy until tuned or was I sent a defective part? I think the posts I read were from ported 87mm TB, this is obviously larger since it started life as a 95mm. Thanks for your help.
