I ended up going with a different set of 60lb bosch injectors, just had to swap the pintle caps to the longer style. Much easier than machining the manifold and zero risk of a local machine shop ruining my shaved/polished manifold trying to figure it out, lol. Ive already had its initial start w/ the Haltech ( http://instagram.com/p/cAOqIWh3G8/ ) , just sorting out an ignition issue currently.
Speaking of, if anyone reading this wants a set of never been used 6 50lb 14mm oring injectors once owned by Turbo Tom himself, PM me haha!
I talked to the FIRM guys during the Tioga show, seemed liked they were eager to get people out to the track. Eventually I would def like to take my car out there, maybe once i get a good tune on the haltech.
Sorry for the off-topic post, good luck at Sebring though! Eventually I'll have to check out the yellow 510 in action
