306 to be tuned and dynoed

[thirsty1101]

Hey folks, I posted here a few times in the past looking for a Stang, but I finally found a clean 89 LX. Thanks for all the help in doing so. My dilema is that I will be bringing it to Laroccas' for a full tune and dyno within the next month and I am looking for some input. The motor is now a 306 with forged pistons, milled crank, Track Heat intake (upper and lower), Trick Flow Twisted heads with 1:6 rockers, F-cam, Edelbrock 70 mm throttle body, 4:10's in the rear, a AOD with PA components and a TCI Street Fighter converter with 3000 stall. The complete tune will be around 675.00 with a chip burned, this includes the dyno. My concern however is whether or not this set up will work in harmony. If any changes need to be made to make this combo work better, I need to do it before the tune and chip or else I will need to blow another 675.00 for changes made after the tune. Is any one out there running a similar set up? I purchased this car with this set up, all except the TCI converter. Any guesses on the dyno numbers? I believe the headers are BBK, no cats with a H-pipe. Thanks in advance. Thirsty. Forgot to mention 24lb injectors.

id save your money . Jus play around with fuel pressure and timing is the main thing until you boost. Ive heard stories about chips not being worth it until you boost. but thats jus my opinion

That dollar figure is exceptionally high, dont forget you can no longer change components once the chip is burnt, so you better be sure you finished modding that car. For the 700 I'd be looking for a laptop tuner tweecer or another brand to enable you to continue to tune as you add or change components. My guess for your output would be in the 270-280 range to the wheels.

Around here you can get dyno time for about $100/hr and tune it all you want yourself in that time. Thats all you need. Just to check a/f and adjust timing and fuel. Unless you are rich I would save my money.

I wish I was rich. Im just trying to get a good tune to make the car as reliable and safe as possible. The car actually came with a Crane Cams Interceptor 2 hand held computer, but it is not hooked up. I think that thing would serve better as a paper weight these days, Im sure its obsolete software by now. Well, this is why I posted, got some good advise and hopefully will save myself a few hundred bucks to put elsewhere. Thanks again.

Another quick question. Won't my stock computer still think it has the stock engine components? Will just playing with the timing and fuel pressure trick the stock computer? I know Fuel Injection is awesome, but carbed engines just seem so much less complicated. I guess everything good has it's price.

As much as it pains me, I'll have to disagree with ole DMAN here. hehehe


Sure... the initial cost can run between $600 and $700 but lets keep i mind that the largest part of that cost is for the chip itself. Once the chip is yours, it won't cost you near that amount of money to get it retuned. In a lot of cases, you can get a deal on re-tuning from the folks that you bought the chip from. Expect to pay between 50 and 100 bucks for a retune if you make major modifications after the initial burn. That includes the dyno time.

valid points...just comes down to how much you want to spend to maximize the output. If 'safe is what your after then 40psi and 14 initial timing is 'safe' but to find the engines potential you will need some roller time (or tuning software)...again, how much is it worth to you. For myself...older guy who FINALLY was able to build the motor I wanted, and who really sees limited driving time, this engine is my last...the parts are staying, and my tune was money well spent. The gains were excellent but again the price was significant.
Daggar...you make excellent points.

Great advise. The car came with a Crane Cams Interceptor 2 computer, but it is not hooked up. The previous owner had the computer set up for the bottle but disconnected it when he took the juice out. I know it is obsolete, but better than nothing. I understand that it can adjust the fuel map and timing for a easy tune.

Might be wise to look at the date for the previous post

If I had a dollar for each time that happens I'd order me a new 2020 GT500!

I’d like a dollar for how many times the cranks no start checklist is reposted.
