_ **“man, that looks liek fun. what hp levels is it happening at? this also a problem in the non intercooled regals?”** _ Around 700 to 900 hp\*…same block in 84 to 85 (non intercooled) Keep in mind, alot of this happens from guys like me, 100K+ miles turning up the wick, alot of guys hitting 10’s,some 9’s on stock shortblocks. \*I think alot of times it starts with the crank thrust getting sloppy… _ **“also, blocks shared from gn and the turbo t/a’s?”** _ Yep, called the 109 block _ **“last ?, what is prefered method of manipulating the efi? i imagine that tuner pro has a definition file for the t-buick. basically hook up a prom setup and burn ur own stuff…”** _ Not too much sense in burning it yourself, there are several experts that will give you a great chip (somewhat programable for timing and fuel enrichment with AC switch and a couple dash switch positions) they can even fine tune the chip with results from your data logger This is my personal preference (also the $$$ goes up as you go down the list). . .
