I had an STS kit on my car for almost 3yrs... started out at 472/501 and ended with 515/535... you have to crack the whip on that tuner and tell them to make sure that it is WAY safe... don't sacrifice the motor for a little more performance... just my .02

Well i had the car tune & they said they put a safe tune on the car i guess that wasn't the case. I have 42 lb fuel injectors on the car & i do have a upgraded fuel pump. The engine is already out of the car & im doing a 370 forged engine forged pistons Forged connection rods Forged crank the whole deal. Im actually having someone look at the PC on the car & having the fuel injectors looked at too see what exactly went wrong. Like 99Z28LS1 said about the tune if thats the case im a little pissed at the fact that they didnt make it a safe tune. What should i run boost at with forged engine?

No matter, who tuned it, you should be monitoring it. Babysitting a FI car is part of owning it. What do you use for diagnostics?
I ussually use an aeroforce guage, to monitor knock retard, (and everything else) and at times wide bands, egts, and etc etc etc etc...

I agree with you slightly. For people that arent mechanically savy or diagnostically educated or experienced, the average "semi" knowledged car guy cant do that. especially with slim wallets like mine

The 250$ for a gauge to monitor knock keeps the piston intact.
pistons= 550 or more....a forged 370 = 3000 or more.......seeing the knock retard and taking your foot out of it before melt down.......priceless.

I thought the pcm was to monitor the knock sensors & changes the timing according to the knock. Is there an external knock sensor that can monitor the knock???? I would of thought 42lb fuel injectors would been plenty of fuel with a 255 fuel pump & was told there was a safe tune on the car. I will be finding out more information when the PC is sent out & having my fuel injectors flow tested.

i was running 9 PSi car was at 460 RWHP. If you want it too be right on it would 571 Crank horse power would be pushing the 42 fuel injectors to there limit. BSFC is the amount of fuel your engine uses to make 1 horsepower for one hour. It is usually between 0.42 and 0.58 at wide open throttle. Normally aspirated engines with efficient combustion processes are at the lower end of the BSFC scale [~0.45], supercharged engines tend to be towards the higher end [~0.55].

I made 540rwhp through a 4l80e with my 42/48lb injectors and one 255lph pump at about 12psi but was running out of fuel past 5500. I have ran as much as 14 on the street though for short bursts. New fuel system is in as of now though.
I also have an aeroforce scan gauge and a wideband to monitor everything though.
