The motor is a ITR motor with Endyn 12:1 pistons, header, stock cams, stock head port, chipped P28 Skunk program.
We installed TWM ITBs on it today.
310s ran like ****. Too much black smoke.
270s ran decent, but still sputtering and smoke.
240s ran okay.. no smoke, but still some hesitation.
We've tried different fuel pressure settings from 19psi up to 40psi to no avail.
The plugs were fouled, so we put new plugs in and it still sputtered. Could it be the Skunk program? Is there any unknown trick that I haven't heard of?

Also, what should we do about the PCV system? The car does not have an aftermarket catch can. Is it a necessity?

Also, does anyone know how to cure the problem with the throttles sticking occasionally? Different spring? Are they available from TWM?

Thanks for any help. Much appreciated. Keep in mind I've been out of the game for a long *** time, and I am a dumb *** when it comes to individual throttle bodies. I'm a rookie on this.

I've helped otu mad people with advice, so maybe someone can throw me some knowledge. Thanks again!

 

Thanks mike maybe we can figure these things out

 

You must be slipping kiddo

 

ok, skunk program runs really rich

next,

TWM uses a newer spring/chain(whatever it is) to keep the throttle plates from sticking open. they fixed the problem after many people reported this happening.

if those are jared's itb's those are the older version, so you would probably need to call TWM and get the newer piece.

 

Mikey! How I've Been looking for you!!!!

I'm gonna send you an IM

!!!!!! hope you reply!!!!!

Using a preprogrammed off the shelf ECU program, of course larger injectors will run too rich. That needs to be tuned for real.

It didnt fix the problem. only made MORE problems.

you need to get a programmable ecu.

 

2 more weeks steve. we gotta meet up and drink a beer or six.
i got your parts. later.

 

anyone else got a suggestion?

 

with all due respect, typically you wont find anyone who knows the answer to publicly provide it - as its how some of the more experienced tuners make their money. understandable, and again all due respect to all.

 

Mike, my buddy wants to buy your car if it's for sale. I know the Toda's were for sale a while ago. Maybe the whole car is now.

Take care brother

 

i already mailed him the answer and any tuner worth a **** should always be willing to help his current and former customers out with advice or knowledge. Thats why cheetah are vapor trail are top notch

 

thanks Shark tank for all your help.

customers = spend their $ to get the service... hence my post. no harm intended, calm down.

 

no problem, just saying if you are going to be a good tuner, you shouldnt charge an arm and a leg for just some help and answering a few questions. should they charge good money for their expertise on the dyno and building and installs, yes...but knowledge should be shared in most cases

 

i agree with both of you guys. you both have valid points.
thanks again for all the replies.
