cfm tech

[85burbanator]

how many people here use cfm tech parts on the 350 motors? im thinking of getting the powerplate, hi flow ported throttle body, injector spacer and fuel pressure regulater. should i splurge and get everything? just wondering if anybody with any or all of these products like them, wish they didnt get them etc. educate me. thanks

I have not yet gotten all of their parts but I do plan on it. I have the injector spacers and the tbi power plate and am just waiting for more money to get the power charger, in line fuel pressure guage, and adjustable pressure regulator. I should have them by after christmas though. I asked the same question recently and everyone who responded that had those parts told me that they noticed a very large power gain. Most of them hadnt measured the mpg yet, but I expect it to go up just like it did for trucks magazine. There are quite a few people on here who speak very highly of cfm tech's tbi upgrades. After I put mine on, I will let you know.

I wouldn't buy those kinds of parts from anywhere else. Every other place is a rip off as far as price goes. $100 for a little hunk of aluminum, yeah right. I had a TB spacer on my burb and noticed no difference. It may go back on when I put the new motor in but more cause I have no idea where the factory TB bolts are

square deal people.. I have their spacer unit on my BB v3500... 2/10 of a mile per gallon better... real world... (after doing the suggested air intake mods)
Im going to use them on my frame off sb v3500 build up... I want to rebuild stuff anyway and their parts make sense to me for the money... they actually DIDNT try and sell me stuff I said i would buy but made the right SUGGESTIONS on free theings to do to tweak...
theyll get my return business
Mention ck5.... I did andthey seemed interested about us... maybe we will get the good guy discounts at some point...
FYI.... a big name vehicle manufacturer is now using them

i just did all that last weekend... did the ported throttle body, powerplate, injector spacer, adjustable regulator, gauge fitting and the Hypertech powercharger..

i decided to do as much of it as i could afford at once. really, the only thing i didn't do was intake and injectors.. kinda regretting not doing the intake while i was there. i'll hold off on injectors till i go 383..

definitely a little seat of the pants power gain. bone stock 350. i swear that powercharger works great.. little pricey for a salad bowl, but it flows a ton of air...

really wants headers bad now, ya can feel it...

added prolly 3" in height between the powerplate and powercharger..

the powercharger is one of the upgrades I have planned. Bit much for a bowl like you said but thats the one piece I really see working. I port my own throttle bodies(not as good as the ones you buy but it helps). Between the ported TB, adjustable regulator, RV cam, injector spacer, salad bowl, and headers, I think i will have a decent TBI 355.

the motor in my blazer is a 350 bored 30 over (makes it a 355 right?) with a mild cam and 194(?) heads. if i get the cfm stuff will i have to reprogram my computer? i guess i can ask them that question but maybe some body on here knows about it. also going to be swapping the thorley headers from my sub to the blazer. should be a good setup.
