I have great news if anyone who did not already know this.. the LNF upgrade from GMPP, you know the one that EVERYONE says "you cant tune on top of the upgrade" or "you can tune on the upgrade" well i am gonna clear the air for those like me who want info on it!!!!!! YES! You can tune on top of the LNF GMPP offers. i spoke to a GMPP dealer that is close to me. Of course he did not know much, but.... he gave me a number to a guy who purchased it from him and when i spoke to Andy he said that you indeed can tune after the upgrade without hurting the flash you get from the upgrade. IN FACT you have to do the upgrade, not necessarily gm's but the upgrade to a three bar map, if u want more boost/ high power the HHR he installed it on, which is the same as our beloved cobalt, plus a cat back they fab at his shop and his dwn pipe made 290 hp and 360 tq TO THE WHEELS..... GO GM! GO COBALT!

 

hmmmmmm
dunno???

 

hmmmmmm
dunno???

 

290whp and 360tq.. is horrible.. something is way off

And your reading made me dizzy

 

Wrong...you do not have to have the GMPP tune to have another tune. Just get a Trifecta tune or any other tune from somebody reputable on here.....the 3 bar would be nice but its not necessary. I and many other members are pushing 22 lbs with the stock stuff. I myself put down 307/361 with a trifecta tune, muffler delete, and dejon intake.

 

im not saying you have to have it but i know when ur pushing serious numbers the three bar is an important thing. my friends hatch civic had to have a 3 bar for the amount of power were making there. but we are pushing 20 psi and running 11.4 quarter times

but i guess hondas are diff. on that hhr there was no other tune so i think it wasnt a bad pwr rating per say but a decent one. i like the plug and play part of tunes not f-ing with fuel curves and things cuz i am daily driving. i want it all to be bolt-on mods along with a plug-n-play tune should i go for the hahn one then??

 

about 2% of the members on this website will need that 3 bar

 

I've been selling the one for the HHR's, etc, and it does come with a code to be able to get it flashed at the dealership, yes.

You can find all of the info about that particular one on my site

I just heard the Cobalt LNF stage 1 kit is out! part #20090401 look it up.

 

You know I had the number highlighted and almost hit copy! Almost got me haha!

 

L.P. HOW did you do your muffler delete? did you have to just cut it off i can't find ANY BOLTS

 

Part# for the 3-bar?

 

You cut it off completely and replace it with a straight pipe welded on along with the tip. Costs usually less than $100 bucks.

 

Ok, I was actually stupid enough to look it up for you guys. Then I see someone else caught that it was an april fools joke. I am dense.

 

The stock TMAPs are good for about 24.5 psi, are you pegging that much boost?
The 3.0 bar TMAPs are good for about 28.8 psi

For most of us, the 3.0 bar TMAPs are unnecessary.

 

well i dont think i want that kindd of boost thanks for helping me out though this post was just something i posted cuz i see alot of ppl arguing over the tunability of the gmpp uprade and wanted them to know it is tuneable, but i am glad for the info on what boost range the stock can get.

thanx to all of u

 

well according to this we can upgrade with bolt ons to increase power after the stage kit.
but I dont want to draw conclusions until we actually see it
