hi im pretty new to the whole tuning idea and i hear that is how you get the most hp out of your mods.My Set-up:-S13 blacktop sr-Cometic Head Gasket-GT2871R Turbo-Megan Exhaust Manifold-Apexi intake-Apexi exhaust with 3'inch piping (no cats)-Blitz Downpipe-CX Racing Intercooler-Greddy BOV-Koyo Radiator-Denso 550cc injectors-Z32 MAF-Tomei Turbo Elbow

and im hoping to get at least 300whpi live in Cali so does anyone know where i could get a good tune for cheap?thanks,

power fc, enthalpy, e-mancewith that turbo and set up, and lets say 740cc or 850cc inj, and a 260-264 lift camshafts you could be right around 380-400 at 20-22psi

I vote Apexi PFC... You can get the main unit with controller for under $1k and it's fully controlable.

I think 300 whp is a moderate estimate and if you go full standalone you'll push upper 300s

well the things is that i really dont wanna buy a stand-alone. is there anyway i can get a descent tune without one? i am just looking for around 250whp because i just want it to be a daily driver that can rip on most of the cars on the streets.

You tell them what you have done to your car and what boost you want it tuned for. You send them your ecu and they should sent it back to you around 2 days after they get it. Hook it up to ur car and ur good to go.

Some people have had VERY bad experiences with Jason/E-mance.

Idk if he's even still doing tunes.

EFI specialist is the next cheapest at 300 bucks. I have an EFI tune running my KA-t and it's great. Turnaround time was a little longer but it's cause I'm on the east coast and he's on the west.

If you are comfortable tuning it yourself then get Nistune, it's basically a stand-alone system that uses your stock ecu. If find a reliable dyno tuner then they can most likely tune your car using Nistune.

i must sound like a huge dumbass right now but how much is a Nistune and is there places where they tune them for you?

okay.... don't tune a car via mail..... take it to a real tuner with a dyno for the best results.

This is so right, i dont understand people who reccomend a flashed ecu for a "TUNE".

A boosted motor is sensitive to air/fuel, i bet the tune's these guys ship out could be enhanced by at least by 40% on a dyno tune...this means a better runing motor..more power...and the reliability factor of a flashed ecu doesnt even compare to a dyno tune...Get your heads out of the gutter guys.

Save and put some insurance on your build with a real tune

This is true, everything matters from temps, inches of IC piping, exhaust, barometric pressure, fuel line size, regulator, pressure, oil pressure, AFR, diff gearing.

Get it tuned not flashed. Tuning usually rund 400-700 bucks

a lot of people get the JWT or Enthalpy tune and then fine-tune the AFR's with a SAFC on the dyno. Timing is a big part of tuning a boosted motor as well, not just AFR's. A good reliable tune will have conservative AFR's and pull a safe amount of timing so your engine doesn't go boom.

I have a JWT tune running for a good 3 years with no problems. I dyno'd my car a while back on stock internals with 135,000 miles on the engine and it made 270whp and 280 tq at 11 psi with a t3/t4. My AFR's looked like they stayed around 13.5-14 so it wasn't running to rich like most people say JWT tunes run.

you are right spooled 240, this is working for you but what you have done with your safc, do you think this guy will know what to do if he follows your path?

I would just hate to see his motor get killed when for instance, he is detonating and thinks its something small and decides to drive into town that night and ends up raising hell and cracks a piston gland or something, when if he knew of this sputtering popping at a certain rpm was severly bad and was about to cause a disaster, then he could had avoided it.

I haven't touched my JWT tune, I just had it reflashed for 600 (steep i know) got it back and popped it in. People say the tune is really rich but on the dyno i was around 13.5 AFR which is pretty good IMO. Every car is different as far as how it will run but to a certain extent the mail order tunes have worked for many people including myself. They usually have conservative AFR's and timing retard so you might not get every last potential hp but you will have a better chance of not blowing your engine, overheating, etc. I daily drive my car and i usually get about 27 mpg on the freeway and 30 if i drive like a grandma lol.

Definitely nothing wrong with the dyno tune which is probably better, but mail order tunes have worked wonders as well.

I'm running solely my mail order tune and it's working great. Eventually I might get an SAFC and fine tune it on a dyno, but my AFR's are great right now and I'm happy with the power that it puts out. I recommend mail order tunes because people usually try to tune SOLELY with an AFC and they blow up their engines because it they didn't do anything about timing. An ECU tune compensates for timing as well as larger injector sizes.

13.5 AFR cruising or under boost?

under boost, i know 12.5 is more of a conservative and safer AFR but 13.5 is still fine. My car has never detonated or overheated with this tune.

Even with my stock ka just the 555cc nismo injectors, z32 mafs and the JWT ecu felt way faster and more responsive than the stock ecu. They optimize the fuel maps and the timing even off boost so it's not just some piggy back module.

hey there is a JWT ecu for a redtop sr20 with 550 cc injectors and a z32 mafs for 250 bux on zilvia classifieds in the "Bakersfield Hook up thread"...dunno what would be the difference in the ecu between a redtop and a blacktop tho
