wow yah I totally forgot about that Andrew. His belt was very very easy to put on compared to mine, might want to check that out. But yes you can upgrade the exhaust but that wont fix the power loss, I ran stock exhaust for awhile with no problems. Put that money towards fixing the car

 

slipping belt...interesting

 

hmm, good point andrew...ill find that out. However im pretty sure the boost stays at 120. I'll check tomorrow when we get the car on the dyno again. I just emailed cobalt addiction about the issue and hopefully i get a good answer back.

 

I know i'm quoting an old post haha but just sayin that guy doesnt know what he is talkin about.. lol cause I got my tires replaced at dartmouth surplus for my stock 18s

 

they might not have had any in stock at the time. I know they get shipments all the time, wait a week and go back. I got all 4 of my tires for like 550 or something.

 

Guy i talked to said "no we dont have those...been getting alot of Cobalt and G5 drives asking for that size, we dont carry those.

 

ahah what an idiot, you dont need the exact size you can go for a 40 profile tire or go for a wider one.

 

Exactly Chad. The stock 215/45/18 tires size is not near as popular a size as the 225/40/18 that are far more readily available, they are almost identical in actual height, just slighly wider for better handling. There are lots of available 225/40/18 tire combos out there. Shop around I got my tires for $550 tax in for all 4.

 

I went to Dartmouth Surplus a month ago and they didn't have
tires then, I went to Star Tire on Sackville drive , they gave me a
good deal on 4 tires..just a thought.

 

Well ill deal with the tires sometime in the winter when its about time to change back to normal tires. Anyways, on another note i decided to tint my lights tonight. Heres some pics, i know my car is dirty as hell and i didnt have the right mode on my camera for night time so the pics suck but you guys get the pic. BTW ill be heading to the shop tomorrow at 3:00pm to get james to mess around with the tune to see whats up with the idle. And possibly new plugs.

 

looks nice!

 

Look great

 

yea it does look awesome, except for the sparkles on the lights....told my friend to get clear coat....he got clear coat with glitter effects so now my side lights and one reverse light has sparkles in it

 

So I did some comparing of the GM stage 2 tune to what we have now and it looks like there are some differences in the torque management section. Specifically under the spuercharger section. There are four tables, Max Boost 1st and 2nd gear and desired boost when in and out of steady state. I am going to play with those tonight and see if we can get this figured out.

 

Got busy last night and never had a chance to email you some compare files..will do that tonight

HPTuner forum is a great resource as well, just go to the website and click on the forum tab, also check out the tuning section here on css.net, both have great info!

 

I will need to get my car tuned James and so will another member on here from New Brunswick. When would be a good time? It needs to be on a weekend and how much to flash my car with the stage 2 tune, nothing else no playing around with it just need the stage 2 tune.

 

i like the lights would like to know how ya did it! shoot me a pm on details.... and i think it's better if you get a more torque output then whp! u can feel the tq more then hp

 

you wont get more torque than horsepower with these cars. I found I picked up torque with the meth. As for the lights there is a how to on the site somewhere

 

yea theres a how to on the site, i went by that. I bought 2000 grit sandpaper. Washed the lights, sand it down, washed them again, taped off parts i didnt want the paint to hit....did 3 light coats and then fucked up on the clear coat cuz it was the wrong type so i have to redo 3 lights and put another layer of tint on cuz i want them darker. And chad why do u want stage 2 if u r going to stock?

 

I am going back to stage 2 lol.

 

Snakes709 you have mail..sent some tunes for comparison sake for ya....i used multiplers to dial in my tune, however gonna do it right after the weekend by using histograms to get the comanded a/f dead on. I can email you the updated tunes after, but try to use those tunes i sent to figure out whats wrong with your car

 

yeah i know it's really unlikely to have the torque close to or higher then hp, just saying you'll feel more torque more then having more hp, if u can follow what i'm saying might sound a little confusing

 

I know, thats why he needs to get some meth. car felt a ton faster with that and the new tune

 

So did you get the drop off issue fixed?So at the point of dropping off,do it go lean or ???Any issues with MAF over voltage?
Anyway you can datalog the pull and post a screen shot of the PCM data here?

 

brad at double z has a meth kit for sale! $300 i guess it's designed for the ss cobalt
