Is this TPI worth it?

[xeniadrums]

I was offered a TPI system for $400. It also includes the computer and wiring harness for it? Do you think this is worth it? Why or Why not? Thanx

if it\'s all there and works then yes

Depends on your motive. If you\'re looking for streetability and economy with a daily driver then I\'d say yes, good deal. But if you\'re looking for performance and not worried so much about it as a daily driver then don\'t bother with it.

Is it an aftermarket or stop harness? either way check the harness for buchering someone may of tried to install it and messed it up and there trying to recoupe there losses, Also if its a stock harness your going to be doing a lot of work to get it running and may consider getting a aftermarket harness and computer for around the same price.



As for performance I can tweak more ponies with a computer and still have a very streetable vehicle even with a wild cam using a computer then a carb not to say there bad but you really have to know what your doing when you tweak a carbs setup.



Personaly I like to beat the little ricers at there own game http://www.s10v8.com/images/smilies/icon_wink.gif because theres nothing more powerfull then displacement!

One of the biggies to look for is wether it includes ALL of the sensors and relays and esc. They can add up to a small fortune (I know). Also is it a MAF or MAP system? If it is a MAF it is more adaptable to different engines, but make sure it includes a working MAF. No sales pitch intended here, but if you do need one, I have a brand new one I\'ll let go cheap. If it is a MAP it will work best on a totally stock engine - the one it came on or an identical one. Both styles can have chips burned for different applications.

I\'ve seen some pretty reasonable ads lately for custom chips, but if it isn\'t a reputable company be careful. The wrong fuel or ignition profile can burn a piston pretty quick. Also try to get the injectors for the correct engine size. 19# for 305 and 22# for 350\'s. Changing them can be costly (I know). These are a few of the things learned the hard way. It is a sweet setup when done right. Here in WI on a zero degree morning after sitting a week I just touch the key and it\'s idling smooth as a baby\'s butt instantly. You can pop it in gear and go, no hesitation. Not that I recommend that, but you can do it. Now on my 79 350 4 barrel Suburban for comparison. Actually,

I wouldn\'t try when it\'s zero. http://www.s10v8.com/images/smilies/icon_wink.gif

i just think you can get more power out of a carb motor than a injected for less the money.

take a stock TPI engine and a stock carbed engine both of them being a 4.3 for example there both around 160 ponies for around 448$ you can get a good 670cfm carb that will knock your ponies up to 225hp with the right mods but for only 125$ you can get the same hp with a chip for the tpi version.



then theres the other benefits to TPI quick starts and starts in below freezing temperatures fuel economy when you want it and performance to match. sure putting in a custom harness and computer costs more money then dropping a carb on the top but it more then makes up for it with saving reliability and performance!



just my ramblings! http://www.s10v8.com/images/smilies/icon_biggrin.gif
