What are the mod recent mods you have made ? Have you tuned for the stall?

 

Can you post your tune?

 

yes retune by a good tuner

 

Listed above are all my mods...i got it dyno tuned last week...my tuner installed a walbro fuel pump because my stock one was given out at 5000 rpm....it runs and shifts good the tq locks up at 50 mph...I told him to do a engine and tranny tune

 

How many ls cars has he tuned? Was it a dyno tune street tune or both?

 

hes tunes alot of ls engines, he has a 1400hp twin turbo vette that he tuned and hes done many torquer 2 cam installations he uses a dynojet, his web site is East texas muscle cars.com I think he knows what hes doing

 

have you talked with him?

 

Yeah i talked to him he believes that there could still be a fuel problem...Do you think it could be my injectors still have the stock size injectors?

 

Are you saying your car went into 2nd gear, then lockup at WOT? Is this the first time its done this? When my tranny first went out a few years ago i was at the track, it felt good in 1st gear, then when it shifted in to 2nd it felt like it was loosing power, but it still had tq management at the time and i think since the 2nd gear band was slipping the computer was cutting engine power to help save to poor thing, is your fluid clean and pink?

 

I'm certain your injectors are way past there limit. I don't know if that's the reason for your problem ,but rid of those stockers ASAP!

 

tuner should know what the injectors duty cycle is at. That should have been addressed while tuning. Can you post the tune?

 

i have heard of others having some issues with that guys tuning. One person in particular that had lots of problems and a dog *** slow camm'd car but had a dyno sheet that said 430 HP. I personally met the guy and he seemed very nice and professional, and seemed easy to get along with. I also had my own tuner with me the day of the dyno.

 

hmm, yup went into lock up in second gear then i let go and hit it again and all the power was there....i dont get why it only does it at the track on the street i can do any kind of roll and it pulls hard through all gears including 2nd...I dont have my tune to post it up...transmission fluid looks nice and pink and doesnt smell burnt or anything

 

lock-up is controlled by the computer.

 

i dont know but if i dont figure out the problem im goin to yank this pice of crap automatic and put a 6 speed in it im tired of all the trouble. i spent alot of money in this car and i just want the damn thing to run right.

 

check your duty cycle on your injectors. with a 228 / 230 cam and a Vig 4000 i was at 97% duty cycle. Not saying its THE problem. But i'm quite certain it needs to be addressed

 

do you think 6 speeds are maintenance free bc they aren't

 

no but i got one with a stage 3 clutch that was running good before a drunk bitch rear ended my *** and toatled it....and i got this car with an auto for 1g...idk im just tired it not running rite

 

my tuner couldnt find anything wrong with it he dynoed it 3 times in a row and it put down 432 every time....I took it to the new track in crandal TX awsome track btw... i put a full tank of gas in it and it ran good my best out of 3 runs was 7.6 @89mph in the 1/8 and 12.0 1/4 @110mph with a crappy 1.69 60ft leaving @ 3000 rpm i was hopeing to be a little faster but im just glad the thing made it down the track without a problem.
