Yes, it's bad. There may be a multitude of reasons why it is happening.

ohh god that don't seem good are there any common causes of that ?

Get teh damn car friggen tuned for the love of god already.

like crappy gas giving the knock sensors fits and thus the ecm dialing back timing?:facepalm:

Or crappy gas leading to dieseling?

When you put cheap regular gas in your LT1 you get angry!
When you get angry you go try to sell your LT1 for 9k.
When you attempt that, lulz and embaressment happen.
When emabaressments happen you try to get an LS1.
When you get an LS1 people think your fast.
When people think your fast, people wanna see how fast.
And when people wanna see how fast you are, you lose to an LT1.
Don’t lose to a lame old LT1!

:lol:

This thread delivers. :rofl:

just made me laugh but wsex gave me the number of a tuning place today thats closer so i don't have to drive all the way out there with my uncle

i gave him the number to cartek

Oh lawd.

PCMforless, stay away from any local "tuner" that claims to tune LT1s.

This.

whats wrong with cartek?

Nothing in particular, aside from the fact that GOOD LT1 tuners are very few and far between. Most shops don't even bother with the platform anymore.

i know cartek is mostly based on ls
but they also do lts

Don't bother with any other local tuner

Gas was like 3.18 or something round the corner for cash regular.
