If not, then thats your issue.

i did have it tuned... not sure if you want to call it street tuned but it was tuned.

zzp's 8 sec car has a stock high compression gt bottom end........................

with more than 20 pounds of boost........

and thats on a turbo set up that makes more power than a supercharged set up............




should have put more time into tuning.

I mean CUSTOM tune or mail order tune.

It seems a wideband O2 would be really helpful for keeping these engines alive.

it was a mail order tune from intense. it came pretuned to the car.

ZZP is allot cooler and allot more helpful as well. i was just wanted a fast supercharger car, i know it possible to have it done. it really didn't make any sense to have a supercharged car be turned into a turbo. I really just wanted to prove a point. i know it doesn't make any sense now, but that is what i wanted to do.
Like people ask me now why i want to turbo my srt, because i have never had a turbo car. but my connection fell through so that wont be happening either.

o your set up could have went plenty fast.......


im just saying, your set up did not fail because the motor could not handle the power, it failed cause the tune was not good enough.

with ANY build past a 3.4 you should be going for a street tune or dyno tune.

You had an M112 on there, thats multitudes better than an M90 with a 3.4" pulley.

Another thing to note is its IMPOSSIBLE for it to be pretuned to the car since every car is different.

it was specific to the car, from intense i told them the parts the programed it.

hahaha






















happy trolling

It may have been specific to your mods but you have to ask yourself... how many M112 3800's has intense probably tuned? None.

I bought it from them, that is was I am trying to explain. On top of this it was Tucson, I didn’t know anyone that worked on domestic cars really. The guy that I had look at it said the tune was good.
Now my prix now is running a strictly zzp tune and it has been running fine for 3yrs, but i have been wanting to get it tuned, but once again i have no idea where to look. call me stupid, but allot of the guys down here only care about rice burners.

lets see a scan of the tune.............

how???????? what tools i can only open the tunes for my charger..
i dont have the tool to open the computer.
if you can tell me how i will get the tool as soon as i see the car again.

BTW. Thanks for the advice, I will see what i can do to get that information to you.

mail order tunes are ****ing ****. You have to take in consideration that the same tune they give you might go to someone else that lives above sea level or at sea level. A car has to be tuned to its own specific self and weather climate.

A build like that you really need a dyno tune, with someone that knows what their doing.

fwiw my intense mail order tune was dangerously lean, and i got lucky

go back to that guy, since he can clearly read it, it get a copy of the tune

I am sure it ran great, till #3 gave out.

I wonder if the knock sensor picked that up.

Usually #1 will go first most the time. I see that #1 already has a chipped piston too. But I have seen my fair share of #3's put windows in the sides of blocks. Best one was when it went, and took out the pan and the starter when that rod was thrown.

I would say your used block, and a few parts are still of value...to me.


All tunes should be done for the exact engine its connected to. Off the shelf tunes are great for mildly modified cars. ZZP, and Intense PCMs...uh...no. I would stick with a DHP, and I have heard good things about overkills PCMs.

Sucks man. I would order another engine from ED, and swap your parts on over to the new engine, and tune and drive till the next one goes. Hopefully not for some time.

~F~

to the OP my #3 piston did the exact same thing... and chipped #1 and #3 on a stock pulley with minimal mods pullin a fairly long WOT run.
