well yea it runs ok but i feel like i lost alot of power, i need a tune soo badly, i have to rev it up hella to get it going. I need a tune, does anyone around my area have an LT1 edit or can tune my car, im willing to pay them for the tune. I dont feel liek sending my ecu to pcmforless.com can anyoen help me out please???

 

Your car should run on stock tune with the Hotcam kit. Your problem may be more than tuning.

 

Don't think so........you definately need a tune. You have a lot of mods there and they need to work together. Have yuo ever had it tuned before?

 

should run on a stock tune, altough a tune would be better but it should run fine, a buddy had a 230/236 xe cam on a stock tune for a while and it ran fine, is your maf properly hooked up.

 

Should run fine on STOCK TUNE! remember, by putting that Granetelli MAF in there you are most likely screwing your fuel table up quite a bit, try putting your stock maf back on & try that out bud, also check to make sure all your injector wires are on their rightfull injectors & same with plug wires. But yeah, put a stock maf back on.

 

Thats basically what I was saying. Tuning does help, but the hotcam isnt that aggressive and the car should at least run ok with some decent power.

 

My 96 WS6 ran slower after the HOT cam and stock tuning. Even with the HPP+ cam cartridge, only improved by .2.

It wasn't until I got it reprogrammed did it finally pick up. Then got it better fine tuning with LT1 Edit.

You definitely need a reprogram.

 

My car picked up 4MPH in the 1/4 after the cam kit on the stock tune.

Also, it felt much stronger on the street too.

I think your problem is more than tuning.

i think its more than tuning also. my car ran fine on the stock tune.
i lost a littel throttle response and a little low end but picked up w awhole lot in the mid and upprer range. you should go back and douvle check everything. BTW it will run a hell of a whole lot better tuned. i got my program from Ion at madz28.com and its like a whoel different car now.

 

Why do think its more than tuning?

I ran a 13.18@104.9 with the following mods:
K&N, 160 thermo, air foil, HPP+, 1LE driveshaft, and 4.10 gears. Stock everything else including GSC's.

I then installed:
HOT cam, Crane Gold 1.6 rockers, 52mm TB, new pushrods/valve springs, SLP 2OTL, SFC, panhard rod, lower control arms. Best I could do was a 13.20@105.

No changes except for reprogrammed computer, 12.7@109. Changed to SLP dual cat headers, 12.4@111.

Was there more wrong with mine than tuning when it picked up so much after just a new program?

He needs a new program to make it perform. Stock tune just won't cut it.

 

My car went 13.7 @ 104 on street tires.

I added the hot cam and it went 13.3 at 107 with stock tuning. And drove really good on the street.

Got it tuned and it went 12.9 @ 111 consistently. It drove the same on the street as without tuning.

Just something to consider but when I got my hotcam kit installed...the car ran fine but it didn't get very good gas mileage and it didn't feel that much faster at all. I gained about .15 and 1-2mph at the track. I then got my computer tunned by pcmforless.com and at the same time installed a lt4km and 160 stat. Bryan has a system where you can pay more $$ upfront and he'll send you a pcm tunned...you send yours back and you get your money back, at least most of it. I did this and it worked great, I had about 10min. of downtime totall. After the new pcm was in the car was a night and day difference. Ran smoother, better throttle response, better gas mileage, and for sure more power, especially up top. I went from 13.5s at 103 at the track to 13.16@107 with just the computer change. Provided the day it ran 13.16 the weather was very good. I usually ran 13.2-13.3. Bottom line is everyones car is going to run and act differently, but for my tunning was work about 20-25hp.

i know my idle air control gaskets need replacing that cant help me 2 much. i just put the MAF on yesturday, it ran funny for a bit but then ran smoother after about 4 minutes. so no one around me has a lt1 edit to help tune me up locally?? i heard from john foster that there is a guy near me that has the expensive lt1 edit thing that costs like3g's, if he reads this i need your help!

so u guys think i should put my stock MAF back on?? it feels liek this after market MAf makes it so i dont need to rev it as much to get it going off of the line.

 

My car has actually been performing like crap ever since I got my Hot Cam Kit installed.

Eventually I traced the problem down to a slipping trans. However, I still feel like I'm not making all the power I should be. I plan on replacing my Cat. with an off-road pipe in case it's clogged.

Tuning for a cam makes a huge difference no matter what cam u put in. It is something u have to consider when doing a cam. It helps idle, AFR, throttle response, and everything else from driveability to racing.

 

The Seat-of-the-pants racers in here will tell you until you're blue in the face that it runs fine on stock tuning;however, some of us have done before cam, after cam, after cam and tuning dyno runs w/ A/F meter, and a scanner hooked up. Depending on what other mods are done to the car, it may run "OK" on the stock tune. However, w/ certain mods, such as a MAF, you may be running rather lean in some areas such as WOT. I've never had someone w/ a cam buy programming and then ask for their stock tune back......
AS for it possibly being more than tuning, here's a list of problems that I have encountered on cars brought to me w/ problems after a cam swap:
1. Do you have an LT4 KM? I think you said you did. If not, you're getting false knock
2. Did you replace the lifters? Some people get away w/out it; however my experience is that a LT4 HC will colapse weaker lifters, and can wearout good stock lifter in about 2-3K miles if you're shifting high or driving hard.
3. Did you adjust the valves right? This can lead to false knock or partially collapsed lifters. If your lifters have any collapse problems, I've seen a 35hp+ hit.
4. Check wiring, grounds, and tightness of your plugs/wires
5. Check for exhaust leaks. I've had a couple that I couldn't hear but were costing major HP.
That's just scratching the surface. Of course I'm assuming a lot of things were done properly (like the cam installed straight up). Get a tune, dyno it, check the A/F ratio, tune it again, then go to the track. The HotCam does cost you some downlow power, but the track numbers will show you that the power is smoother and more consistant up top.
