Thats extremely rich, but I wouldn't think anything serious could go wrong. I'm not 100% tho, thats just a guess

Don't wana be too rich for extended periods of time gas wash the rings out and unburnt fuel diluting your oil isn't good either

Ok thank you, I'm gonna try to get a re tune soon, can tunes just go bad? I'm pretty sure when I was tuned back in September I was right around 11.5-11.7.

And also, I'm running a 2.9 and my only cooling mods are an ottp h/e w/ optionb, what's the most amount of timing I should be running?

I picked up a TVS this week so looking forward to putting it on the car. It came with a 75MM pully. The person I bought it from is going to see if he can find the others.

My current setup pre install is

60 Lbs injectors
Dual pass with option B
Griffin H/E
3" intake
ZZP shorty header Downpipe and GMPP sport exhaust
Rotated mounts
Also Ill be running 94 octane fuel

My question is should i upgrade to 79's and how much power roughly will I be looking at?

Thanks in advance!

79's are not much more than 60's (look at the rated @ fpsi, more like 72's) Get 80's (more like 93# on our fpsi) or methanol. Power, should be above 300hp or you need a new tuner/sell the setup

Hey guys I'm looking at getting a TVS soon and have a couple questions. I am on 60s and meth right now, could i run a 2.8 or 2.7 pulley with these or do i need 80s. from what Ive read i need 80s but just wanna make sure. Also would i need a return style fuel system and a bigger fuel pump for this or is the stock stuff good enough. Really leaning towards a 2.7 pulley so again i think i need all this stuff but i just want to double check with some experts. All my other mods are in the sig. Thanks

You will be fine with 60's. Unless you go to E85 or build the motor 80's aren't needed. Stock pump will be fine also

I run 50/50. Not sure what devilsown's mixture is but 50/50 works the best all around.

Cooling mods have nothing to do what pulley size you can run. All "cooling mods" recoupe your temps faster after a pull not keep them down.
