What is the best injector size for the TVS? i currently am running 60s with a 2.6 pulley, full cooling mods and a trifeta tune. Vince tells me 80s are a pain to tune. I think i am missing way too much power. car is fast but not what i expected from the tvs. i am at 19 degrees of timing. Any help or suggestion is appreciated

 

just get a br fpr then you wont have to tune for bigger injectors

60's are way to small for that pulley,even for a 2.8 there to small

 

injectors are way too small

 

yay!

 

80s or a return style fuel system. Vince is dumb if hes telling you 80s are hard to tune. I went from 60s to 80s and they tuned just fine for gas and e85. He might be too lazy to get them to work too.

 

your on e85 though... 80's and pump gas are a little more difficult to get right

 

yay once again i hear vince sucks lol. everyone here in wa keeps telln me to have him tune me but i dont feel like wasting 500$ for a dyno tune if he sucks

 

Yeah he told me the same thing with my 80s that whys im running so rich he says there so big he cant controller the fuel. Its only 285 btw email tune

 

WRONG!. Before I tuned for e85 I tuned them for gas so I could switch my tunes back and forth if I needed. They tuned just fine crusing idle and wot.

 

I run rich on 60's so not sure what's up with the trifecta tunes. Wonder if the zzp controller would help with trifecta's tune possibilities on 80's

 

yeah but i live like 40 min from his shop so why have it emailed to me. im just going to stick with the zzp stae 3 can tune for now

 

hes not tuning the maf or ve properly then.

 

ive got my 60's on my 2.8 no problems here even without my meth

 

I'm just stating what Sean told me awhile back when i first bought my tvs.

 

I would get 80s because they leave alot of room to grow. They are also safer when you pulley down so you dont have to worry about 100% + IDC.

 

it also has soo many variables... when guys get to the point of the tvs thier combinations of parts and such differ soo badly and the tunes themselves differ soo much that its really hard to say what works for what cars...

i was just stating that a 2.8 will work with 60's but and this is a big but, youve got to know that you will run out real quick when rpms rise and pulley size goes down

 

Very well put

 

roderick, are you running MAF only tune?

 

Sure am. Its the only way I roll. Why?

 

79's or 80's.

That allows you room to "grow" with the TVS. pulley down.... etc.

60's are "maxed" out on the stock TVS pulley.

 

My 60's were at 76% IDC on stock pulley TVS. I did move to 80's for the hell of it though. Also did the fuel pump rewire. Figured I'd 'solve' any fueling problems before they started...

 

note to file. every car we have tried the fuel pump rewire- the genuineparts on everything including LS s/c says this deal be it kennebell boostapump, racetronix re wire whatever. not worth anything. 2.6 on TVS= bye bye motori

 

What about a 2.7inch pulley on a stock motor with TVS, cause thats what i just ordered along with 80s lol

I dont want to blow it up

 

Thanks for the info John. I hope I'll be OK on the 2.8" then. If I ever decide to run E85, I'll certainly get a return style system...
