Questions about mods.

[afk]

I guess I can make this pretty simple . I’ve been doing a lot of reading on various forms but nothing seems to point out exactly what I’m trying to figure out . So I bought this car used it’s an 06 GT at the bottom of this I’ll leave a list of the modifications I was told the car had . My question is this car supposedly custom tune as looking in the access port shows Tuesday didn’t come with it the problem is I’m not understanding why with this level of modification this thing hold steady at 20 pounds of boost and never anymore . I would’ve figured this car could’ve handled 25 to 30. I’m just curious if someone can give me some kind of input as to if it something I just need to reprogram adjust or if there may have been a reason they did what they did when they tune this car. I’m coming to this from a diesel normally a bigger turbo means more power there’s not a lot you really change other than opening the exhaust up a little more. Anyways I’ll give you a list of what I was told was done to the car


forged pistons and rods, new crankshaft with clevite main bearings. engine block decked and line honed, head decked ported and polished new valves and springs. coemetic head gasket. Act six puck clutch. Fuel pump internals upgraded to high pressure Corksport internals. 4 inch intake. BNR S4 v.2 turbo. Three bar map sensor. Corksport injector seals. Grimmspeed ebcu. EGR delete. One stage colder plugs. Corksport 3 inch catless downpipe to 3 inch corksport exhaust with dual exhaust and mufflers.


Now I can obviously verify the turbo is what it claims to be I can see were the EGR was removed and plated it off I can see the different map sensor . The intake as well. This thing a hold of solid 20 PSI all the way to redline. I’m just curious if given the modifications this thing should be getting a little more boost than that. I’m not saying that the car is slow I’m just saying that my Stock C-4 Corvette would’ve given it a good run for it’s money in those things weren’t very fast. Although boost doesn’t always mean power I just would suspect it would be boosting a lot higher. I’m just kind of curious . I love input and would love to know how to verify the rest of the stuff on the outside. I couldn’t really find a good place to post this so hopefully I found a place where people can give me a general idea . Anyways I look forward to some good chats at least.

From that tomb you just wrote I thought I gathered you don't have an accessport??
Get one, do a log or two, less than 5 -6 minutes please, we could tell a lot more with that then what you think the car may have on it...
And don't you dare reply with more diarrhea, keep your posts short two, just like the logs.

Stock C4 vette is within a few tenths in the 1/4 to a stock MS6. So don't go there. A stock Speed6 with only a tune will send a C4 crying to mommy.

Now, the "problem" you are experiencing isn't a problem. The previous owner tuned it for what HE (or she) wanted. Simple as that. If you want more, re-tune it to what YOU want.

Assuming you have an AccessPort, you'll probably want to hire an E-Tuner to tune the car the way YOU want it. As stated in prior posts, someone likely tuned it a certain way, for who knows what reason.

Maybe they had an aggressive and a conservative tune done. Maybe they just sold it with the conservative tune. Who knows. But it is your car now, tune it how you want.

But you're right, with those mods, you should be able to push more boost if you want. But I assume you'd want to run E30, Meth, and/or Port injection to maximize safe gains.

There is indeed an access port the problem is they messed up the release tabs on the cord on that thing you can’t remove it from the vehicle. I have went to the various tunes that were custom done on the car the other three they have in there that we’re done seem to be even lower results . Yes I’m very aware of this thing should walk on that car all day but is the car sits I have no doubt I could burn it. That’s why mentioned it even start it should’ve have no problem keeping up with it even. Does anybody have any tips on how to get those tabs to release or should I just look into ordering a new cable? I’ve talked to a couple places around here but it doesn’t seem like many people much care to Mazdas around here. It seems if it’s not a gigantic V-8 or lawnmower errm i mean Honda they have no interest. But I’m going to imagine the access port probably has a lot of tweaking in its programming. I wasn’t attempting to insult the car I’m just saying it doesn’t seem like it’s performing the way you would think it would. The previous owner had rebuild everything there’s less than 40,000 miles on the engine tranny n PTO. I don’t know if maybe he tuned it so he can break it in properly but I would think it’s way past that point.

Learn how to spell check and write coherent sentences! Fuck man. You make yourself sound like a 7 year old.

Stop your whining about the power, enjoy it for what it is right now, and pick an E-tuner from this site.

Then read all the threads on aux fueling until you have a solid grasp on what's the optimal setup with your built motor. Then get it tuned.

I shall look in to getting this thing disconnected.

Can you ask the old owner? i know someone on here that when they sold their modded car they put a conservative tune on it so the new owner wouldnt send it into a wall. he planned on letting the new owner know after a month or so and the kid was used to driving it

Datalog..... We should be able to tell you if you have room left for what is happening... Or, pro tuners like said above
