What's up everyone. Popping my first cherry post so bare with me. I have a 2002 Camaro that I revently purchased, it had a comp cam 212/218 with LT's and flowmaster exhaust along with an slp lid. The guy had a good tune and the car made 400hp 405tq to the wheels, the car ran great. Unfortunaly the cam was not good enough for me and the flows had to go. I swapped it for a 233/239 comp cam and TSP true duals. Car sounds like a champ now but doesn't run like it did before, has problems stalling when warmed up and doesn't seem as fast. The guys in pensacola want 500 for a Dyno tune, I don't think swapping a cam would require one. Does anyone know anyone who can write me a tune for my car? I just don't see the need to spend that kind of money just for a cam swap

Huh? A cam is about the biggest need for a tune. A cam changes so many parameters in the engine its not even funny a dyno tune is mandatory. All the issues you're having are related to the cam not being dynotuned. Thats a big cam and a mail order tune will never sort all the issues out. I dont mean to be a dick but if you're not willing to spend 500 on a dyno tune for the cam you should have never swapped it in the first place

 

Yeah kind of a dick. The reason for forums like this is to get advice from other enthusiast in the same field of interest. Never said I wasn't willing to spend the money just was wondering if maybe there was another way around it. If you wanna give advice like that maybe you should have bought a cobra or a civic

 

A tune will do you some serious good, regardless. LS1's seem to net more out of tunes, than just about any other NA engine I've seen!

 

Wow dude...... Little Butthurt I see, I have you solid advice which was that your car can't et by with a mail order tune. It will need a dyno tune to solve your issues. If you had taken time to do some research then you would have found that out. I stated I wasn't trying to be a dick but in light of your response I really don't care anymore. Get the car dyno tuned like tusky said by Geoff or enjoy having a car that runs like a turd. Have a good one

 

Anyways...thanks for the advice. The reason I asked is because I've built plenty of other toys and I know tuners that will save the tune for a car that isn't heavily modded so others can use the same tune since they have similar mods. I'm aware that a Dyno tune is the best way to go I just figured I would explore options.

 

Go get a tune, preferably a proper dyno tune. A lot of tuners will charge you less for adjustments if you have your original tune with them. I really hope you weren't pushing the engine too hard without a tune though.

 

Not too hard....I took it thru 2nd and 3rd just to see the difference maybe to 5k. The tune was from a place called Redline Performace in NC with the 212/218 520ish lift cam. I swapped the cam and the car runs fine you can just tell it needs a new tune. I would go back there but it's 6 hours away and I'm moving to Florida soon

 

212/218 is almost stock. Do not take the engine to 5k again the tune for the 212 is pretty far off and you're risking damage. The afr will be way off as well as the ve table. You changed valve springs with the cam as well correct?

 

From what I remember the oem cam is around 197/198. Yes sir no racing until I get a tune. I replaced the spings/rods and timing set.

 

ok sounds good just get a tune and see but no matter what the new cam will never feel as torquey as the old one did down low

 

That's what they say, right before I did the cam swap I changed the old flowmaster to the TSP td's and that alone made a good difference. The cam I installed made around 80hp on the engine dyno so hopefully with a tune I can squeeze 450 to the wheels

 

What heads are you running? I don't know of too many cam only cars pushing 450. I'm planning on going H/C/I and hoping to get between 450 and 500rwhp reliably. "smog legal" of course.

 

Heads are stock. Forgive me for asking but what's HCI? Guessing heads came intake...with the old garbage flowmaster's hooker LT's an SLP lid w/smooth below larger TB and that mild cam it made 400rwhp. Figured I could gain a little with the TSP's and good amount with the cam. Hope for the best and plan for the worst lol.

 

maybe on that dyno it did. However thats extremely high I'd expect that cam to 375ish. Ideally with your new cam and ods I'd expect you to make in the 410 range whp speaking.

 

Yeah, Heads Cam Intake. What kind of Dyno was that on? I'm not trying to nit pick, that just seems like 8 or 9% higher than I'd expect.

That's what I was thinking, I'm not an expert though.

 

I'm not sure the Dyno make, I'll have to call the shop and ask. I have the Dyno sheet though. Ive seen this happen before, my zx10r seems to make about 5hp more than any other zx10r of the same year. Not every car is exactly the same some have a little more or a little less than the other, maybe I got lucky or maybe the Dyno reads high. I guess numbers don't really matter too much it's just a reference, all depends on how the car runs.

 

Ya I saw in another thread you trapped 110. If the da was not terrible and you spun I'd expect a 360ish number or so. With 375ish I'd say a 115 trap is possible with good da so get some prcatice and you should be fairly close to that. 400whp would be a 118 trap or so

 

The track conditions were decent. I had the car less then a month and first time to the track in years in a car anyways. The tires and fairly new but not worth a damn when it comes to launching. Feathered 1st and when I hit second it got so sideways I was looking at the other car so I had to back off lol. Wanted to see what the car would do with the mods it came with since the previous owner never took it
